In the Crimea, with a Russian-descent majority, there is agitation for secession from Ukraine.

It seems to me that if the inhabitants of the Crimea want to become part of Russia, they should be allowed to do so; therefore, I suggest committing to hold a plebiscite in two years time to decide this.

That will give the Crimeans a chance to see whether the government of Ukraine is democratic and to think about whether they really prefer to be ruled by Putin.
