Really? How many good men or women can one find in a country, willing and able to head out across borders to get involved into a war, solely to sacrifice themselves for the sake of saving others from genocide?

I'm not seeing armies heading out to save Palestine. Ukraine. Any of the African countries currently at war that i know so little about.

Simple truth is that not everyone agrees with this kind of selfless sacrifice.
The US had a small, but growing Nazism political party in its ranks before the war and the majority of those able to vote were against sending troops before Pearl Harbor happened. What do you think would have been the result had the acting US government sent troops into Europe without the approval of their citizens and without the shaming of the middling Nazis among them?

When forcing the issue, without making sure the ones opposing it won't suddenly strike at your back, you only send out more people to their deaths. And instead help the enemy achieve their goals more easily instead.
Nazist America was a real possibility at the time, not just a fantasy.

So yes, moderate, cautious and gradual isn't the evil you want it to be. It's just another route that considers the consequences of failure. And it's not without flaws, principal being the people involved.

Also, you may think I'm advocating for it, but that's just a side effect of my original point. Anything can be a force for either good or bad. Only focusing on the bad points and ignoring the good, vilifies it.

Tell me how that at its most basic meaning is different from what those you claim to hate are doing. Just because the subject of the hatred is different doesn't change the fact that the act of hatred is the same damn thing.

You don't like that things can be both bad and good? That's fine. But what you're pursuing is purity. Doesn't matter which side of the extreme you're looking for, it's still an extreme.
