What an alarmist, not to mention ignorant, statement about history and the nature of the governments involved. There are actually checks and balances in the US constitution that will prevent Trump from being a Mussolini, Franco or Emperor to Putin as your Neo-Hitler. The House and Senate will have a lot to say on that subject.
How long had Germany been a democratic country before Hitler turned it into a dictatorship? How about Italy and Spain? Was Japan a democracy when it joined the Axis?
Your new "global alliance" is about as likely to come about as the second coming, and is based solely on speculation that Putin may have compromising information on Trump.
Do you really believe that Trump can overthrow, during his term as president, over 200 years of democracy and turn America into what was the equivalent of what were fascist dictatorships? Do you also realize that, if there is one thing his base hates more than condescending liberal wanna be intellectuals, it is Russians?
Is it plausible the Russians have some compromising information on Trump? Yes. But read this and tell me, do you think it is enough to turn the entire US government into joining a global alliance with Russia? And if it is just compromising information on Trump, why would Democrats and moderate Republicans join in an alliance with Russia?

Do you really believe that Trump has enough power as President to make a "a new global alliance" with Russia become a reality? Or are you just spreading fake news?
