The 70 days of bombing in the Balkans, the NATO'ization of Eastern Europe, U.S. hegemony in the Middle East, the constant push forward towards the Russian frontier by NATO, the constant overthrow/attempts to overthrow the governments of Russian client states started long before Don Trump ever took office.
Trump sanctioned every Russian client state severely, but more importantly pushed U.S. energy, which directly impacts Vlad Putin in a way nothing else can.
The modernization of the Russian military started before Trump took office and was driven by U.S./NATO policies of the previous 20 years.
Oil is up again today, pumping billions more into Vlad Putin's pocket.
