I don't believe anyone is arguing against the "Who and Why of Now." And it would be preposterous to think the US as a so-called Christian nation has not gone after perpetrators in spades in several Muslim countries. At the same time it is hard to dismiss the actions of the US and others over many decades in contributing to and motivating the enemies of Christianity, embodied by the West, to propagate atrocities in the name of their god.
Don 't take this personally, this is garbage, and your thinking is part of the problem. There are no "actions" Americans have taken that has made islam the especially vile and loathsome set of ideas that it is, and it might be said that Americans only took some action to make the problem worse, to enable islamists, by putting an islam sympathizer into the White House and singularly the most incompetent Secretary of State his agent - in the same way that Americans putting a NYTimes-style-of-the-day fascist socialist in the White House in the '30's exacerbated socialist destructive success in Europe eventually made total war against socialism necessary, should we have wanted to save our country from loss of territorial sovereign rule. Beside ignorant useful idiots like you, there are unfortunately now many at high levels of power and their knaves who seek loss of U.S. territorial sovereign rule with islamic fascists, climate-change fascists, communist and open-society and libertarian anarchists and dopes like you their tools for that.
