Putin's biggest problem on the world stage, besides Russia's second class status is sanctions. Every country in the world has enacted sanctions against Russia because of it's invasion of Crimea. In the first few days of the nascent Trump administration they work to lift US sanctions against Russia.
NATO (The North Atlantic Treaty Organization) was formed in 1949 to protect against aggression from Russia, Trump and Fox whoop up a holy war of misinformation against it.
The Democracies of the world dis-invite Putin's Russia from the "Group of Eight" in 2014, because of it's invasion of Crimea, thus making it the "G7". Trump alienates them all and pleads for Russia to be re-invited.
Putin's Russia is a second class power. Putin can't bring Russia back to prominence so he begins a campaign to destabilize democracies around the world and install "Nationalists" who will act for him. Intelligence services around the world agree that Russia interfered in the US elections to favor Trump. Putin's FSB created a false narrative about Ukraine being responsible and Trump, along with prominent Republicans, echo it and spread the word through Fox News and the GRU's Social Media campaigners.
Putin wants to increase his foothold in the Middle East, so Trump abandons Syria and the Russians move right in, occupying the abandoned US Military bases.
To further destabilize world governments Putin needs a war or two to create chaos on the world stage. Trump pisses off North Korea and China and assassinates Qasem Soleimani. This is the best way to start WW 3 without involving Russia. It also distracts from the impeachment and what He and his Republican cronies are doing to negate democracy in the US.
When no other bank in the world would loan toxic Trump money he was given billions in loans by Deutsche Bank. Those loans were guaranteed by the Russian state bank VTBR. Trump fights to prevent his tax returns from being released, is it for fear of what they might reveal?
It doesn't take much to realize that Trump is working for Putin, probably so his billions in loans will be forgiven.
