Solution: Americans should be driving tanks towards the Russia/Ukraine border right now. Nato needs to deploy 100K soldiers into Eastern Ukraine at once. Make Ukraine a NATO member.
Bad idea ! Putin de strange could take this as an art of war and decide to go full scale bombing on the Americans and all her allies and the war escalates to a nato vs un war and we have a War of the dammed 
We have more than discussed nuclear escalation. Nuclear escalation is a loosing game an Putin is aware of it.
Newer updates seem to indicate that Ukraine is going to be opening a front across the dnipro river. Evacuation of villages and unconfirmed reports of troops gathering in the area seem to indicate that Ukraine may choose to launch some tentative offensive to free the territory in a less costly fashion.
