Wiper inserts usually are less costly to produce than square-back wiper dies, because multiple wiper inserts can be manufactured from a thick-wall tube, and because the shorter and smaller inserts require less material. In addition, changeover time is shorter with an insert than with a square-back wiper die. However, initial setup requires the purchase of the steel holder, and the inserts must be replaced and disposed of more often than the square-back wiper die.

The Vietnam War was a long, costly and divisive conflict that pitted the communist government of North Vietnam against South Vietnam and its principal ally, the United States. The conflict was intensified by the ongoing Cold War between the United States and the Soviet Union. More than 3 million people (including over 58,000 Americans) were killed in the Vietnam War, and more than half of the dead were Vietnamese civilians. Opposition to the war in the United States bitterly divided Americans, even after President Richard Nixon ordered the withdrawal of U.S. forces in 1973. Communist forces ended the war by seizing control of South Vietnam in 1975, and the country was unified as the Socialist Republic of Vietnam the following year. 1  Play video Chicago Seven Conspiracy Trial. 2  Play video Sound Smart: Vietnam War Protests. 3  Play video Nixon Addresses Silent Majority.
