Just like NATO. If the U.S. sudenly pulled out citing its irrelevancy and waste after the fall of the Soviet Union, the rest of NATO would collapse in short order.
The truth is that the U.S. Military and NATO was always planned to be the pitbull Enforcement arm of the Globalists' NWO. However, the U.S. will never place a single U.S. serviceman or woman directly in harm's way in Ukraine. The U.S. Military will not allow itself to get sucked into the WW III which the Globalists had long planned for. And with the U.S. out, the rest of NATO will back off its nonstop war drumming.
