Pope says force is justified against Islamic militants in Iraq

ABOARD THE PAPAL PLANE — Pope Francis on Monday endorsed the use of force to stop Islamic militants from attacking religious minorities in Iraq but said the international community — and not just one country — should decide how to intervene.

Francis also said he and his advisers were considering whether he might go to northern Iraq himself to show solidarity with persecuted Christians. But he said he was holding off for now on a decision.

In other comments to journalists returning from South Korea, Francis confirmed he hoped to travel to the United States in September 2015 for a possible three-city tour: to attend a family rally in Philadelphia and to address Congress in Washington and the United Nations in New York. He said a Mexico stop on that trip was possible. He also said he might make a one-day visit to Spain next year.

On Iraq, Francis was asked whether he approved of the unilateral US airstrikes on militants of the Islamic State, who have captured swaths of northern and western Iraq and northeastern Syria and have forced minority Christians and others to either convert to Islam or flee their homes.

‘‘In these cases, where there is an unjust aggression, I can only say that it is licit to stop the unjust aggressor,’’ Francis said. ‘‘I underscore the verb ‘stop.’ I’m not saying ‘bomb’ or ‘make war,’ just ‘stop.’ And the means that can be used to stop them must be evaluated.’’

But, he said, in history, such ‘‘excuses’’ to stop an unjust aggression have been used by world powers to justify a ‘‘war of conquest’’ in which an entire people have been taken over.

‘‘One nation alone cannot judge how you stop this, how you stop an unjust aggressor,’’ he said, apparently referring to the United States. ‘‘After World War II, the idea of the United Nations came about: It’s there that you must discuss ‘Is there an unjust aggression? It seems so. How should we stop it?’ Just this. Nothing more.’’

His comments were significant because the Vatican has vehemently opposed any military intervention in recent years, with St. John Paul II actively trying to head off the Iraq War and Francis himself staging a global prayer and fast for peace when the United States was threatening airstrikes on Syria last year.

But the Vatican has been increasingly showing support for military intervention in Iraq, given that Christians are being directly targeted because of their faith and that some Christian communities, which have existed for 2,000 years, have been emptied as a result of the extremists’ onslaught.

The United States began launching airstrikes against Islamic State fighters on Aug. 8, allowing Kurdish forces to fend off an advance on their regional capital of Irbil and to help tens of thousands of religious minorities escape.

Church teaching allows for ‘‘just wars,’’ when military force can be justified under certain circumstances.
