Smart people know the miracle election of Trump as president bought the world a few more years of relative peace. Had Hillary been successful in stealing the election in 2016, what we’re witnessing now would have started back then.
The war actually started in 2014 when the US/NATO engineered coup of the duly elected government. Thus began the separatist movement in the Donbass and the uncontested Russian annexation of Crimea. Ukraine has been shelling the Donbas since 2014 killing over 13,000 people.
The Russian second invasion could have been avoided if Biden wanted a diplomatic solution. We had ample warning.
