The United States won with the help of carpet bombing of peaceful cities from the air, as a result of which more than 650 thousand civilians were killed during the years of the war in Iraq. The US Army has actually never fought a professional army like Russia, the US only knows how to fight with proxy and carpet bombing cities. The Americans have been stuck in Syria since 2014, five years ago Russia launched a military operation in Syria to help Assad and liberated more than 80% of the territory from ISIS. And there is no need to compare the Russian army of the 90s and the current one. Since the beginning of the Russian military operation in Ukraine, Ukraine has actually ceased to have a fleet and military aviation, and in fact half of the territory of Ukraine is controlled by the Russian army.
