Iran peace talks set to begin in Pakistan
Iranian and U.S. delegations have arrived in Islamabad to begin peace negotiations. A conditional two-week ceasefire has been established, contingent on the reopening of the Strait of Hormuz and a pause in military strikes. Pakistan is facilitating the talks, emphasizing its commitment to regional stability and a durable settlement. Negotiations remain complex as both sides express mutual distrust and conflicting reports emerge regarding the scope of the ceasefire.

Some introductory summary: Iran and the United States held face-to-face talks in Islamabad, Pakistan, but the negotiations ended without an agreement. U.S. officials said the core sticking point was Iran’s refusal to commit to not seeking a nuclear weapon, leaving uncertainty over a fragile ceasefire that was set to run for about two weeks. 1 3
U.S. Vice President JD Vance led the U.S. delegation during 21 hours of negotiations with Iranian officials in Pakistan’s capital. 1 3
The talks concluded without what the U.S. described as the needed “affirmative commitment” from Iran that it would not seek a nuclear weapon or the tools to quickly achieve one. 1 4
Iranian officials said the talks collapsed due to a “gap” between their views on several issues, and Iran’s foreign ministry spokesman cited U.S. “overreach” while not directly mentioning nuclear weapons. 1
Pakistani mediators urged both sides to keep up their ceasefire obligations and said they would work to facilitate renewed dialogue in the coming days. 1
A conditional two-week ceasefire between the U.S. and Iran was announced, with contingencies that included reopening the Strait of Hormuz and pausing strikes on Iran. 2
The ceasefire was described as fragile from the outset, with negotiations and military pressures continuing alongside disputes over implementation and longer-term terms. 1 4
Catholic-oriented coverage emphasized that the ceasefire was expected to end April 22, with uncertainty growing after the breakdown. 4
The central U.S. demand was an explicit commitment that Iran would not pursue a nuclear weapon or the means to rapidly obtain one. 1 3 4
Iran argued that its nuclear program is intended for civilian purposes. 1 3
The Strait of Hormuz was also a key contention point: the waterway carries roughly one-fifth of world oil and liquefied natural gas, and both sides treated it as central to any arrangement. 1 3
One report said the U.S. military stated that destroyers transited the Strait of Hormuz ahead of mine-clearing work, while Iranian state media reported that Iran’s joint command denied this. 1
Negotiations in Islamabad addressed the broader conflict dynamics, including ongoing fighting and Israel-linked disputes affecting how a ceasefire might function regionally. 1 2
Lebanese officials said negotiators would meet an Israeli delegation in Washington separately, and the U.S. and Israel indicated Lebanon was not part of the ceasefire agreement, while Pakistan said it was. 2
U.S. and Israel positions regarding Hezbollah and responsibility for disarmament were described as part of the wider disagreements surrounding ceasefire stability. 1
Catholic leaders in Rome and Washington condemned the broader conflict and called for peace and dialogue. 4 5
Pope Leo XIV led a Vatican peace vigil on April 11 and used the appeal “Enough of war!” while calling for patient, honest dialogue and stressing the protection of civilians. 4
Coverage also highlighted Cardinal Robert McElroy’s argument that the war fails to meet just-war criteria due to civilian suffering and risks of disproportionate harm, and urged immediate action toward ending hostilities. 4
Pakistan’s foreign minister urged both sides to continue upholding ceasefire commitments while facilitating renewed efforts toward dialogue. 1
U.S. officials left Islamabad with a “final and best offer” framed as a “simple proposal” and said they would see whether Iran accepted it. 1 4
Separate talks involving Israel and Lebanon were also reported as expected in Washington, according to the coverage describing different ceasefire interpretations for Lebanon. 2
Does Catholic doctrine support diplomatic ceasefires in nuclear conflicts?
Yes. Catholic doctrine gives strong support for diplomatic ceasefires in nuclear conflicts, insofar as a ceasefire is a morally acceptable means to protect the common good, stop escalation, and open a path toward dialogue and lasting peace, rather than treating force (or nuclear deterrence) as the only road to stability.
The Catechism teaches that “because of the evils and injustices that all war brings with it,” the Church requires that we “do everything reasonably possible to avoid it.” This is not naïve pacifism; it is a serious moral obligation to seek peace using appropriate means, especially when the stakes are catastrophic (as in nuclear warfare).
At the same time, the Catechism affirms that the common good includes peace as “stability and security of a just order,” and that legitimate defense belongs within authority’s duty to secure society “by morally acceptable means.” A ceasefire—aimed at stopping violence and creating conditions for just settlement—can fall under those “morally acceptable means” because it is a practical step toward securing peace, not merely a pause in violence for its own sake.
The Church’s prayer for peace in the liturgy also underscores that peace is a gift to be implored for “in our day.”

Pope Leo XIV has recently pointed to ceasefire-making as a concrete element of the peace process in an active conflict. In a press conference, he expressed hope “for the possibility of dialogue between Ukraine and Russia,” and then added that “there are … concrete proposals for peace” and that—through dialogue and relationships among states—efforts could “promote dialogue and a ceasefire, and find a way to resolve this conflict.”
That is important because Catholic support for ceasefires is not presented as mere humanitarian window-dressing. It is framed as part of a dialogue-based peace process that pursues a genuine resolution.

Recent Catholic teaching and diplomatic messaging emphasize that peace cannot be reduced to force, especially nuclear force.
Pope Leo XIV, addressing the diplomatic corps, cites Augustine’s point that “peace is only possible through the use of force and deterrence” is a persistent error; instead, peace requires “continuous and patient efforts of construction” and “constant vigilance,” including efforts by “the countries that possess nuclear arsenals” to follow up nuclear arms-control obligations (he specifically mentions New START).
The same theme—moving away from escalation logic—is also present in Pope Leo XIV’s World Day of Peace message, which frames peace as “unarmed and disarming,” rooted in the prophetic vision of turning weapons into instruments for life (e.g., “beat their swords into plowshares”). That direction strongly favors negotiated pauses (like ceasefires) and arms-control steps because these actions reduce risk and open space for real reconciliation rather than permanent confrontation.
Additionally, a Pontifical Academy appendix summarizing Pope Francis’s teaching states that “the use of nuclear weapons, as well as their mere possession, is immoral”, and that deterrence “inevitably ends up poisoning relationships … and obstructing any possible form of real dialogue.” If deterrence corrodes dialogue, then a ceasefire that enables dialogue and stabilizes the situation becomes morally consonant with the Church’s aims.
Catholic episcopal teaching likewise urges movement away from reliance on nuclear weapons for security, calling for diplomacy and arms-control agreements as steps toward greater disarmament, including “measures of disarmament based on dialogue and multilateral negotiations.”

Catholic doctrine does not treat ceasefires as automatically virtuous in every abstract scenario. Rather, the Church’s teaching gives the moral framework to judge them:
In short: Catholic doctrine supports diplomatic ceasefires in nuclear conflicts as part of a moral strategy aimed at stopping catastrophe and enabling real dialogue toward just peace, while evaluating each ceasefire by its contribution to those ends rather than by whether it “looks” like strength.
