Baghdad had a warlord dictator for a leader, and a military that had been in a war with Iran and Kuwait. The Ukraine had a former comedian as a president; and their military had been unable to do anything about Russia's invasion of the Crimea. The scenario where a "shock and awe" invasion along 4 fronts causes the president to flee for his life as Russia waltzes into Kyiv largely unopposed to puts in a new government was certainly in the realm of possibilities.
