So far, Putin has accomplished most of his objectives in Ukraine.
He has unblocked the waterways in the Dnieper River to return the water supply to Crimea
Stopped the invasion of Donbass and other Russian speaking cities in east Ukraine. 100 000 Ukrainian troops were on the border ready to invade Donbass. 16 000 residents had been killed by Ukrainian shelling since 2014, ignoring the Minsk Agreement drawn up between France, Germany, Ukraine and Donbass.
Destroyed and captured a large number of the Azov Nazis in the process of demilitarizing Ukraine.
Destroyed 32 foreign Bioweapons laboratories, 6 of which were run by the US military.
Destroyed many of the foreign sex trafficking organizations in west Ukraine, including child sex trafficking.
Destroyed many of the foreign human organ harvesting facilities in west Ukraine which included organs from babies and young children.
Destroyed many foreign illegal drug-manufacturing chemical factories.
Will put a stop to US money laundering.
Will put a stop to Ukraine selling donated lethal weapons to other countries.
Will put a stop to the pending manufacture of Nuclear-weapons. (Ukraine has the largest nuclear plants in the world.)
The conclusion is, Putin will have to move quickly to take control of all of Ukraine (by taking control of Kiev) to achieve all of his objectives before the American weapons arrive.
