Comment: Putin's little green men were Russian soldiers--this is no civil war!
We are also not helpless! "We must support Ukraine--if Putin could have "successfully" walked all over Ukraine and get away with it he would have done so!--He has been upgrading his troops which were in sad shape at the outset of the war on Ukraine and moving them closer into position so that it might be more possible now.
If you want to be a helpless ostrich then keep your head in the sand--you'll eventually get kicked in the butt!
