The US Military was in Afghanistan 20 years. It has been in Iraq, in one form or another since The Gulf War, and was in Viet Nam for almost thirty years. Perpetual war is what the US military does best, and Putin has put his military through the meat grinder at an unsustainable rate. As a result, Putin's axis of rogue states, ( Iran, N.Korea) have supported Russia directly with weapons, and are supporting proxy military organizations, such as the Houthi rebels, Hamas and Hezbollah, in order to distract focus by the West from the war in Ukraine.
