What did trump do that benefited russia?
Undercut NATO, attempted to stop weapons deals with Ukraine secretly and illegal beyond what is allowed but the executive branch, pushed discredited propaganda that Ukraine had undermined out elections, pushed turkey to Russia and then pulled out letting Turkey and Russia crush the kurds enhancing Russia's footprint in Syria and guaranteeing turkey will not move towards the EU in our lifetime. Publicly supported Russia keeping Crimea, his aides removed GOP platform language that supported Ukraine, repeatedly use the bully pulpit too. Spread Russian disinformation that hacking wasn't actually happening even though 2/3 of all attacks happens from Russia including ones that have targeted our hospitals in Americans have died from, had his team call up Russia before he was president to undermine the sanctions from the current president Obama, pushed to remove all sanctions on Russia, pushed to return Russian diplomatic sites in new york to Russia even that they were suspected of being used as spy bases and were taken after crimes, gave the Russians classified information Unilaterally that Even GOP members said probably exposed the source of the intelligence, thanked Russia for kicking out our diplomats, undid sanctions on the oligarchs, congratulated Putin on an election win after he basically dismantled a fair election and appointed all of his own governors. Solidifying further power and reducing Russia's democracy, tried to undermine sanctions following the skripal poisoning, blocked John Bolton from mentioning the 10th anniversary of Russia invading south Ossetia, regularly praise pro-Russian leaders and Europe while undermining traditional western leaders in Europe, supported the Communist invasion into Afghanistan by the Soviets, invited Russia to the G7 summit and pushed for their return to the G8, directed the CIA to share intelligence information to Russia, ordered US troops to draw down in Germany.
I dunno a few more I'm sure.
