Final answer:
Mikhail Gorbachev and Ronald Reagan were Cold War leaders with restraint and negotiation skills who played a significant role in easing tensions and eventually ending the Cold War.
Step-by-step explanation:
A leader with restraint and negotiation skills during the Cold War was Mikhail Gorbachev, the last Soviet leader. Gorbachev initiated policies of openness and political reforms, known as glasnost and perestroika, which aimed to improve relations with the West and reduce tensions. These policies eventually led to the end of the Cold War.
One effective leader during the Cold War was Ronald Reagan, the President of the United States. Reagan implemented a strategy of confronting the Soviet Union, but he also engaged in negotiations with Gorbachev. Their meetings, such as the Reykjavik Summit in 1986, played a significant role in easing tensions and eventually ending the Cold War.
