Confronationalism
It should also be mentioned that Saakashvili seems to be "picking a fight" so to speak with Russia, creating one crisis after the next:
The wine import problem
Moving troops into Kodori
Arresting Russian officers for espianage.
Each one of these events (and a few others) were (or are) conducted with the least amount of tact possible, the objective in all these cases seems to be the provocation of the Russian government. 
As this is a very real trend in Saakashvili's foreign policy, it should be mentioned in more detail.
