So how do you explain invasions of Georgia and Chechnya?
Russia was not threatened by EU and NATO expansion, putins dreams of a resurrected Soviet Union was.
Terroristic threat from Chechens who revolted back then how many bombings have they done how many terrorist acts are they associated with? Countless.
Georgia well Georgia attacked the Russian areas ask George W. Bush if he asked them to attack but Georgia attacked and had their backsides handed to them.
