Even as tensions between the United States and Russia fester, there is one surprising place where their military-to-military contacts are quietly weathering the storm: Syria.
It has been four months since U.S. President Donald Trump ordered cruise missile strikes against a Syrian airfield, after an alleged chemical weapons attack.
In June, the U.S. military shot down a Syrian fighter aircraft — the first U.S. downing of a manned jet since 1999 — and also shot down two Iranian-made drones that threatened U.S.-led coalition forces.
