The USA and NATO are idiots and they break treaties they made with Russia left and right..
According to an article in Der Spiegel, a newly discover documented dated March 1991 shows that discussions between the West and Russia made it clear that NATO would not expand past East Germany an agreement that it appears to have reneged on.
The military standoff between the Ukraine and Russia stems from the latter’s demands for NATO to curb its expansion in to Eastern Europe, in what it sees as a threat to its security.
The key text in the minutes from the meeting quotes US Assistant Secretary of State for Europe and Canada Raymond Seitz saying: “We made it clear to the Soviet Union, in the 2+4 talks, as well as in other negotiations that we do not intend to benefit from the withdrawal of Soviet troops from Eastern Europe,”
“NATO should not expand to the east, either officially or unofficially.”
