Mostly Jesus argues for peace to the point that our powers that be have to make jus bellum arguments to justify going to war, say in retaliation against the 9/11/2001 attacks or the expansionist campaign of the German Reich.

Personally I thought it would be a bold move of faith for George W. Bush to forgive the attackers and then request an act of good faith from the Taliban, say requiring them to charter and enforce human rights for all (including women, non-Muslims and apostates) or face a NATO backed military intervention.

But no instead we got a broadly defined war on terror, a nonsensical axis of evil and attacked Iraq and tortured people for no good reason, demonstrating the US is, indeed run by spoiled plutocrats. The US is in a sorry state

Notably, when Simon challenges Jesus to war against Rome (an abusive imperialist regime if their was one), Jesus is pretty clear that's not the Christian way.

When Peter stands to defend Jesus from arrest in Gethsemane, Jesus points out that's not how we do things.

As such the Church had to commission monks to write books of equivocation to justify that wars and regime changes the Holy See wanted to support, and it depends on those sophistic arguments to this day when the CDC wants to recommend a military response.

A more honest response might be Jesus condones no act of war, but we cannot afford to not respond to this threat to civilization. I suppose it would reveal the Church has multiple masters, but it does that anyway with money.
