I mean, I am the source. This was my personal experience while serving in the military.
But if you want official reports to back up what I experienced, here’s you go:
I was working in an Intelligence unit when Trump was president (not the one directly briefing him) and it’s all anyone talked about at the time. They had to be extremely careful what information they shared with him because he would just go and post details on his social media accounts.
My unit had to change a lot of their missions and coordination because Trump would expose our secrets online. It ruined a lot of ongoing missions we had planned, and we had to scrap and rebuild a lot of our programs after he blabbed about them.
Trump fires top US general in unprecedented Pentagon shakeup
This was more recent, after I retired. But he basically fired our top military leaders, then made his own suggestions for replacements, completing ignoring the official promotion system we have in place.
He didn’t want people with years of experience and exemplary service to lead our military, he just wants his own loyalists in charge so he can control the military. He nominated highly unqualified people for the positions, with the only seemingly common quality being that they were loyal to Trump.
He was also annoyed at how hard it was to replace key people and wanted to circumvent official processes so he can hire and fire people at will, like his old businesses.
In the US? Democrats vs. Republicans.
According to the rest of the world, the US doesn’t have a left party. Democrats are right wing and Republicans are extremist right wing. The left is completely unrepresented in our government. Both major parties lean conservative (from a global perspective) and care more about helping major businesses and the rich elite than actually representing the people.
That’s why there’s a whole movement centered around “no war but class war.” The American people are not actually represented and are instead pitted against each other in this fake “red vs. blue” distraction so we don’t actually go after our political leaders, or weed out the source of the money behind the scenes that dictate their actions.
