We don't make the decision to go to war the government does that without our input. The public supported for the war in Iraq after the government decided to go to war then spread propaganda saying that Iraq was related to 9/11. Those are graphs of how effective propaganda was on those polled after the government made a decision to go to war... we don't vote on that shit.
It doesn’t matter that public support shifted later - of course people feel bad about doing something bad after the fact.
That is the propaganda losing the battle. People found out that the person (supposedly) responsible for 9/11 was in Afghanistan and had nothing to do with Iraq.
Vietnam was the same but it took longer for the general public to find out the truth. The government decides to go to war and spreads propaganda everywhere about why we needed to go to Vietnam. Propaganda weakens as real information about the war spreads then people no longer support the war.
Americans are not just inherently warmongering people I don't think any citizens of any country are.....unless their government has a super effective propaganda machine constantly brain fucking them into being that way (see Russia).
I’m sure that the people in your social circle do disagree with those wars and do disagree with some of the more recent things which have happened, but you need to understand that sometimes the majority does sadly support some very bad things
My social circles? I live in the Midwest there are people in my neighborhood with flags up that say "Fuck Biden Don't blame me I Voted for Trump" in their front yards here. I have seen the worst of Americans and they are not the majority even here. There are some dumb fuck gravy seals that cosplay as soldiers and act like war is a solution to anything and everything but most of the people here who support Trump and have that "America first" mindset are just well meaning morons that fell prey to propaganda.
I am well aware that propaganda works champ the idea that there are brief periods of support for such things somehow cancels that the majority of the time the majority of everyone doesn't support such things is moronic.
