Gundam Wing - Ep07 HD Watch

"Scenario for Bloodshed"

The five Gundams all gather at the New Edwards Base in an attempt to kill the higher echelon members of OZ, but they discover too late they have been tricked; Heero has already eliminated the pacifist leaders of the Alliance while Lady Une and the leader of OZ, Colonel Treize Khushrenada, manipulate the only survivor, General Septum, into declaring war on the colonies (before they kill him too). The Alliance is overturned from within and OZ takes over as the new ruling power.
