Multipolarity Was Triggered By The 2003 US Invasion Of Iraq
On the night of 19-20 March, 2003, the US air force began bombing the Iraqi capital, Baghdad. The EU and NATO were deeply divided on whether to join the aggression: While newer NATO members from Central and Eastern Europe were in favor of the war, European heavyweights Paris and Berlin opposed it.
The Iraq war also marked the onset of diplomatic coordination between Moscow and Beijing at the UN Security Council (UNSC). The two countries began in 2003 to apply similar voting patterns in the Council, first on Iraq, then on Libya in 2011, and over Syria in several key votes. That early Russia-China UN coordination has, 20 years later, transformed into a determined joint policy toward “guarding a new world order based on international law.”
