Desertion, slackness, and alcoholism are major problems in the Commonwealth army. Especially hard-hit were pensioners, most prominently retired military officers and bureaucrats, who had literally been the first in line for everything which was available. The national governments are understandably reluctant to underwrite pensions for a foreign power. Latvia and Lithuania have plans to introduce their own currencies. With only occasional exceptions, each nation thinks of itself first.
Cooperation is minimal.
These nations are too small to provide every type of university specialization, every type of technical training center. To give but one example, veterinary training is very expensive and must concentrate on problems unique to the Baltic states. It is would be much more practical to have one world-class center, with individual special study centers in each country, than three underfunded programs trying to cover everything for small groups of students. These nations already have a common language. Unfortunately, it is Russian.
