Climate change is their false religion.
Pretty sure climate change won’t matter when nukes begin to fall.
They wanted a weak figurehead, like Biden and Obama, who will say and do anything they want, like a puppet. They got what they wanted.
An added bonus to them is the insult to the American People and the USA, like making Caligula's horse a Roman senator. It gives them something at which to snicker, and it reassures them that half the US electorate serves as their useful idiots, so weak-minded, easily manipulated, and stupid as to let America's enemies get away with anything, even the most blatantly absurd, such as the placing of Joe Biden in the Presidency.
Obama was bad. The acceptance, even adulation, of him by a large percentage of the US population emboldened America's enemies.
Biden is worse and an even greater insult to America and reassurance to her enemies.
They are testing their ability to manipulate the useful idiots in America to see how far they can go. They have every reason to believe that their evil objective, the destruction of the USA, will be successful.
They have every reason to believe that they can install an even more ridiculous person in the Presidency and can succeed at flagrant election fraud, that the US press will serve as their praetorian guard and parrot their propaganda, and the feckless, incompetent, morally and intellectually confused Supreme Court, whose clueless justices are among the worst of the useful idiots, will do nothing.
