Understand the propaganda pamplet says NATO is defensive, but I disagree. For instance, there was nothing defensive about NATO bombing Serbia in 1999, or NATO bombing Lybia in 2011. U.S. should declare mission accomplished and leave NATO.
Awhile back I commented here on Free Republic that NATO was purely a defensive organization. Then someone came along and corrected me. He pointed out that NATO went on the offensive in Serbia (1999) and in Libya (2011). Just as you mentioned.
Those two events sent out waves. They gave Russia reason to believe that NATO wasn’t purely defensive after all, and could be used for other purposes.
In both cases NATO believed it was defending innocents against atrocities from brutal groups & dictators.
Nor did NATO attempt to conquer Serbia or Libya, they remain independent.
teevolt: "U.S. should declare mission accomplished and leave NATO."
Vlad the Invader's actions in Ukraine and threats against many other countries manifestly prove that NATO's mission to defend Europe is very far from accomplished.
