Obviously you've not been listening to Putin and Lavrov. They have made it absolutely clear that taking complete control of Ukraine is Putin's objective. Putin has said openly that the end of the USSR was a tragedy and needed to be reversed.
Russia has spent nearly 5 years attempting to conquer Ukraine. The result?
1. Destruction of Russia's economy
2. Two more members of NATO in response to Russian aggression
3. Europe finally rearming
4. Ukraine inventing a whole new way of warfare
5. Massive Russian casualties
6. The nation without a navy, Ukraine, has destroyed 55 Russian navy vessels.
No one was pushing Russia around. They have killed off so many of their soldiers that they are employing North Koreans to fight for them and to staff their factories. Russia has deceived many other nationals, offering high wages but sending them to the front lines to die in a couple of months. All this is well documented.
America has shamefully betrayed Ukraine. America committed to defending Ukraine and Russia promised not to invade. As a result, Ukraine gave up its substantial nuclear arsenal and long range bombers. So it had little chance to defend itself when Russia occupied Crimea. Ukraine is getting financial help and military hardware from Europe. What Ukraine really needs is weapons to defend against ballistic missiles. It will come eventually, but meanwhile Russia attacks mostly civilian targets. Mr Trump is best buddies with a war criminal. It is sickening.
Interesting take.
