Asia Times:
November 13 was a busy day in defense diplomacy. US Secretary of State Mike Pompeo wrote to Egypt’s defense minister, warning America’s closest Arab ally that it could face sanctions if it proceeded with its purchase of Russian warplanes. On the same day, Donald Trump met Recep Tayyip Erdogan at the White House, where the US president again urged his Turkish counterpart to give up the Russian S-400 missile-defense system purchased earlier this year, or face sanctions.
The threat of US sanctions now hangs over two allies – and all because of Russian-made weapons.
