In a blatant attempt to test NATO unity and President Donald Trump‘s resolve as leader of the free world, Russia launched an unprovoked aerial drone incursion into Poland overnight Tuesday into Wednesday. At least 19 Russian attack drones broke into Polish airspace from Ukraine and Belarus, some ranging many miles into Polish territory. NATO forces shot down four of them.

This is a serious test of the West by the Kremlin. It requires a prudent but firm response.
