With Russia acting more and more agressive lately, it's worth considering another possible trouble spot that could lend itself to Putin's quest to expand Russian power. Apparently within the small country of Moldova, the Trans-Dniester province has separatist ambitions. According to news reports, "the dream of joining Mother Russia is now stronger than ever."
The area used to be part of the Ukraine under the Soviet Union. It has proclaimed independence which is so far recognized by no one. But there is Russian involvement in the separatist movement. Some speculate that Russian support for separatism in Trans-Dniester is just a ploy to pressure Moldova against joining NATO. But who knows? Unfortunately the circumstances surrounding the breakup of the Soviet Union, and the dissolution of communism in Eastern Europe provide many opportunities for Russian meddling. You never know when and where the next crisis will erupt.
