An amendment to the Ukrainian constitution declaring that Ukraine will maintain neutrality and never join *any* military or economic alliance with foreign nations would actually be prudent. The only hope Ukraine had for remaining whole and peaceful was to maintain neutrality and accept its position as a buffer state between the EU/NATO and Russia/CIS.
Had they enshrined this in their constitution to start with, there *may* not have been the US-backed armed putsch ousting their democratically-elected president, sparking off a civil war and loss of Crimea. All that loose talk from Vickie Nuland and her pet Ukrainians about joining the EU and NATO and turning Sebastopol into a NATO port was reckless. On the other hand, perhaps *nothing* would have deterred Miss Vickie the Cookie Lady.
Vindman will stomp his feet.
