Russia could shoot down a U.S. aircraft if a no-fly zone were imposed over Syria, National Intelligence Director James Clapper said Tuesday.“I wouldn’t put it past them to shoot down an American aircraft if they felt that was threatening to their forces on the ground,” Clapper said, speaking with CBS’ Charlie Rose at the Council on Foreign Relations in New York about several national security issues. Russia has deployed a very advanced and capable air defense system in Syria and would not have done that if it wouldn’t use it, Clapper said. The Obama administration has refrained from setting up a no-fly, or safe, zone for civilians in Syria partly because of the complexity in staffing and enforcing it and the potential for direct military confrontation between the U.S. and Russia. Democratic presidential candidate Hillary Clinton has called for a no-fly zone over parts of Syria. Republican vice presidential candidate Mike Pence has also called for a no-fly zone over Syria, but Donald Trump, the GOP presidential nominee, has yet to take a firm position. It's like the Obama administration is stuck on Russia, so that they don't have to talk about Wikileaks. The sad part is only a small minority of Americans understands how very dangerous rhetoric against Russia like this has become, because most Americans don't understand that a war between America and Russia means nuclear war...Since well we are the biggest nuclear super powers on the planet. The rhetoric against Russia has become more dangerous this very hour, as now the Obama administration is claiming Russia will shoot down US jets...Which likely has US military personnel freaking out, because well Obama is literally putting our military in a dangerous position with Russia towards the election. To this day the Obama administration is pushing for war with Russia for one reason now, to take Americas eyes off of Wikileaks and others...To simply protect themselves from being exposed further.
