Bad news, Ukraine is over, they aren't joining anything..... This whole thing is about the obscene corruption of Biden, and Ukraine, where Obama and his "point man" on Ukraine(hint his first name is Joe)sparked a coup d' tat against the lawfully elected, pro-Russian Ukrainian president in 2013, then they got an actor elected to the job, an actor totally beholding to the USA and its money, and whom never ceased lobbying for Nato membership. In this whole Ukraine matter, Putin is wearing the white hat, Biden and both houses of the totally corrupt US congress, the black hats!
Putin told them for almost 15 years what he would do if they attempted to incorporate Ukraine into Nato, and nobody listened to him, with but one singular exception, Trump! This is why Putin took no aggressive actions against them while Trump was president and its why the totally corrupt two houses of the congress did take action, against Trump. I might add, that it was Obama and his point man, who motivated their new Ukrainian vassal to wage war upon the separatist regions back in 2014, those two regions are predominantly ethnic Russians, and as soon as Putin saw Biden cheated into office, he knew what was coming, and here we are...
