How did the cold war change under president reagan? check all that apply.

The United States of America has taken the initiative.

Explanation:

During the reign of the Reagan administration (1981 - 1989), the US stepped up its weapons and spent more money. Most were spent on defense military system. Some military analysts said the Soviets would increase the number of missiles for this purpose. Investing in the military resulted in the US taking over the initiative in the Cold War. The Reagan administration blamed the Soviets for instability in third world countries, thus turning to pro-American countries that provided military and financial assistance, most notably Salvador.

The Reagan government also assisted anti-Communist insurgents who fought against allies of the Soviet Union. In the first half of the 1980s, American initiatives dominated. Soon Mikhail Gorbachev came to power in the Soviet Union, who found the state of affairs in his country bad. The economy of the Soviet Union was poor, the population was demoralized, and foreign policy looked bad. Gorbachev was aware of the situation, so soon his administration is launching negotiations with the US to find a compromise solution.
