During the Cold War era despite the confrontation Soviet Union and the United States put a lot of efforts in order not to let nuclear conflict to happen. However George W. Bush started to erode these agreements when he quitted from Missile Defence agreement with Russia in 2001. Nowadays another Republican president Donald Trump continues Bush's efforts to put the world on the edge of a global conflict by imposing economic sanctions against sovereign countries in violation of international law and breaking such important treaties like The Treaty on Open Sky and Intermediate Range Nuclear Forces Treaty. Moreover he wants to ruin New START, the treaty on arm reduction signed during the presidency of Barack Obama. Is he competent enough to be the president of the United States?
