Trump works for Putin, and Putin is not your friend. Putin's interest is to disrupt a strategic enemy, the United States, and he will support anyone that helps him do it. There is no ideology behind this, only a need for Putin to protect his power to avoid ever being driven from power or held accountable for his own crimes. The only thing that makes Trump unique is his gleeful corruption and his ability to appeal to the stupidest people in America. Trump is Putin's butler. Putin funds Trump, and he funds BLM, and he tricks Neo-Nazis to hold pubic rallies while also funding antifa groups, and he organizes anti-immigrant rallies, and he supports Bernie Sanders and Jill Stein, and he funds secessionist movements in the states no matter how crazy they are. He will help, he will fund, anything that makes Americans hate each other more, no matter what it is, not because it advances any moral agenda, but because it damages an enemy. This is why Trump is always injecting his toxicity into issues unbidden. He doesn't care even a little bit about the flag, or patriotism, or the troops, who he routinely insulted during the election. These are things he only just barely managed to pretend to pay lip service to in the campaign. But he knows that it provokes strong, opposing reactions from different groups of Americans, and that serves the larger goal of dividing the country. Because that's what his paymaster wants.
And we're all falling for it.
