Apparently, there IS a treaty.
Treaties don't matter when American neocons and NATO warmongers are trying to provoke a war.
Ask Libya and Serbia.
The difference here is that the neocon punk is insulting the Russian Terminator: "Nice night for walk? Harharhar RIIIPPPPP!"
IMHO, since Russia has ignored its treaty obligations with Ukraine, Georgia, Moldava, Kazahkstan and pre-war POLAND, Poland has no “duty” to PRETEND that Russia will act in good faith in ANY negotiation.
