One of the key criteria for a just war is that the war must be a last resort.  We must exhaust other avenues. It behooves us to make every effort to avert the necessity of outright war.

All other avenues have been exhausted, really since 9/11. It's long overdue. In fact, it's dereliction of duty of citizens and God-serving people. God will not help those who don't help themselves or aren't willing to make personal sacrifices.

It is better to choose a commendable war than peace which separates from God.
~ St. Gregory

FYI: There will be a "Stop the Steal" rally at every State Capitol buildings tomorrow at 12 noon (although it may have a different name, depending on the organization that is running it locally). There is a website with more details, if someone has that please put it up, otherwise I will try to find it when I get back home.

In the case of an eventual war, there's not a side that really favors Catholicism. The leaders of any eventual war are not likely to be Catholic, and therefore truly Catholic principles will not be a guiding force. Catholics will, instead, be required to follow a Protestant leader, such as Trump. Are Catholics really going to give their all (including possibly their lives) for a supposed Protestant/extreme capitalist victory? Because such a victory, if it happens, will not have enduring Catholic principles behind it. And we'll still have the some problems of Americanism and extreme capitalism. Those won't go away, even though the Marxist faction of extreme capitalism may appear to be defeated for awhile (though it will never completely go away if the current form of capitalism is still allowed to prevail).

As much as I support Trump, there are limits as to what I'm willing to give to my support to, since Trump isn't Catholic and he doesn't understand how true Catholicism works.

Nevertheless, if we look at his behavior, he has an innate understanding of Just War as explained by the Church.
