Gorbachev
Explanation:
Gorbachev is more important in the ending of the cold war because of the following reason which includes:
1. Gorbachev is the fourth leader during Regan's Presidency and he is the one that initiated the truce.
2. Gorbachev declared openly unilateral criteria to reduce the country’s armed forces by 500,000 soldiers and soldiers from Eastern Europe
3. He also claimed in the UN in December 1988 that Russian under his leadership will not be using an international class struggle.
Thomas Jefferson's idea of how slavery could be tolerated in a nation that trumpeted liberty had to do with the fact that he felt it was a "necessary evil" that must continue long enough for the US to develop properly. He felt as though blacks were inherently inferior and therefore needed "guidance".
