Putin is el presidente for life, invaded and annexed the Crimean peninsular 3 years ago, started a civil war in Ukraine then supplied, funded and directly supported the rebel faction with Russian soldiers, has been interfering in American democracy by hacking the DNC and releasing dirt (because Trump was their preferred candidate), sends monetary support to ultra right groups in Europe and anti-EU organizations, and runs a series of "independent" international media organizations with the aim of spreading misinformation to their own benefit.
The current goal of the Putin administration is to undermine the post-cold war international order and reassert Russia on the global stage. It wants to restore as much of its old empire as it can without provoking war with the west. This means dismantling NATO and the EU if at all possible, as well as trying to get pro-Russian leaders in other countries who will restore relations and trade with Russia after the west started enacting trade restrictions and personal embargoes to officials in response to Russian aggression in Europe.
