The American President has a history of being extremely flattering of leaders who run oppressive regimes

A big example would be US sending Task Force 74 to attack India when they were trying to stop a genocide in East Pakistan (Bangladesh) initiated by West Pakistan.

India didn't even wanted to have a hand in the war and was struggling with its own problems and would had cared less for West & East Pakistan, unfortunately for them the refugee crisis of 10 million on their border was way too much to handle.

West pakistan just needed a reason to attack India and they did when India started providing aid. This gave India an ample opportunity to divide Pakistan which in-turn was beneficial on a geopolitical point of view.

If the Russian nuclear sub hadn't appeared India might had been possibly nuked or lost that war and West Pakistan might had eradicated the East Pakistan completely. India was late though as highly educated individuals, scholars, teachers were targeted and ethnically cleansed to cripple the upcoming generations which is still prevalent now in Bangladesh.

From this I'd like to ask how could you attack another Democracy for a dictatorship even after knowing the neutral party is trying to stop a fucking genocide!!

This is indeed the biggest failures in US Foreign policy. So much could had been achieved if US had not thought about making India its pawn. This is where Russia won as they didn't believe in the policy of "If you're not with us, you're against us." This is the reason that the only country to share its nuclear tech with India without having a second thought is Russia. They won something that has lasted decades. Its called "Trust"
