although many nations around the world strongly opposed the prospect of an american invasion of iraq, most eventually joined the u.s. in this war

According to US, to "disarm Iraq of weapons of mass destruction, to stop Saddam Hussein's backing for terrorism, and to liberate the Iraqi people," the invasion was need of hour.

Since the extremist Islamist organisation known as the Islamic State in Iraq and Syria (ISIS) significantly extended its power and influence in the region in the latter half of 2014, Iraq has been a major topic of discussion in the international community and in the media. The US invasion of that nation and ISIS, which has recently emerged in Iraq and Syria, in the insurgency against the ensuing US occupation, back then in the form of al-Qaeda in Iraq, can be linked to the political unrest and drastically worsened security environment that characterise modern-day Iraq. However, why did the US initially invade and occupy Iraq? Even now, there is a contentious argument.

The main argument was that toppling Saddam Hussein would be a show of US military power against a visible foe, which hawkish elements within the Bush administration and the military establishment believed was necessary to deter others and dispel any perceptions of weakness in the wake of 9/11. (Karon, 2011). According to Daniel Lieberfeld's explanatory viewpoints on the Iraq Invasion, this concept is driven by realism and was intended to "keep unipolarity, sustain hegemony, and avert post-9/11 decline by displaying U.S. willingness to employ force" (Lieberfeld, 2005).
