When President George W. Bush ordered the invasion of to overthrow Saddam Hussein in 2003, he took a largely unilateral military action. His stated purpose was to increase US national security . Presidents Clinton and Obama favored more multilateral efforts when intervening in countries such as Kosovo and Libya. Is there a justification for the US to engage in unilateral rather than multilateral military action overseas
Not really, every time the USA has tried military action overseas in the modern era, it usually failed and resulted in the country suffering bad set backs.
