What was the significance other than the obvious harm to us forces of the terror attack on the uss cole in 2000

:) during the cold war, people were afraid of communists, both outside and inside the united states. the red scare and mccarthyism that grew out of these fears were damaging to the american way of life. during the mccarthy years, many of the freedoms guaranteed in the bill of rights were limited. write a paragraph explaining what lessons can be learned from the mccarthy era about what u.s. citizens need to protect in order to preserve the democratic political system and the american way of life.

During the cold war, the united states was involved in certain regional conflicts due to fears later called the domino theory, which stated which concept?
