NATO at the behest of and with the United States, has promoted and supported (including military assets) radical and organized criminal Muslim groups in Serbia, Kosovo (including insurrection, rebellion and separation), Bosnia, Georgia, Ukraine, and Greco Macedonian states.
Additionally, NATO had knowledge of the US movement of weapons (some Geneva prohibited) and materials to Islamic terrorist groups in Obama supported "Arab Spring" insurrections featuring Libya and Ambassador Stevens' murder.
Did you notice the NATO response to 9/11? Technically the US was attacked by the ruling party, the government, of Afghanistan. According to the treaty, this attack required an immediate and forceful response by ALL NATO signatories.
What happened?
The Canadian military sent special forces immediately (without notifying the Canadian government, but that's another story), and regulars later on. The UK also responded. Australia, not a NATO signatory, sent special forces. The rest sent basically token forces on non-combat assignments. A very tepid response and a further nail in the coffin.
