Stalin had to make peace with the Russian Church when the Nazis invaded. So too the left will realize that the Right is useful when the Russian-Chinese-Iranians are at the door and our fancy weapon will not scatter them like they did to Middle eastern armies in Iraq. I remember one battle where a US tank commander stated it was good were faced the Hamurabi Republican Guard tanks (Who broke off there attack, retreated and were wiped out), And not the Herman Goering tank division that would have kept coming even in the face of US firepower.
Unlike Stalin had to make peace the democrats operate more like Mao the government takes all.
