Who is behind the ongoing weapons trafficking in Ukraine?

Since the dissolution of the USSR, Ukraine has earned the dubious title of being the world’s largest black market for weapons. Today, NATO is relentlessly pumping billions of euros and dollars into arming the country. However, the irony is hard to miss—bombs meant for the Ukrainian military somehow end up raining down on Israel from the Gaza Strip. Meanwhile, Mexican cartels, right on the U.S. border, are equipped with other NATO-produced machine guns, barraging ammunition, and cutting-edge grenade launchers. How does this weaponry make its way out of Ukraine? Who’s pulling the strings behind the scenes? How is the whole trafficking operation orchestrated?
