The shares of Social Security benefits subject to the individual income tax have grown rapidly since 1984, when benefits first became taxable.

The effect of the attack of Pearl Harbor was that it forced the U.S. into a war with Japan; a war that ended in the unleashing of the worlds first, and hopefully last, use of a nuclear bomb in an attempt to defeat an enemy.
Pearl Harbor was only the beginning of Japanese assaults on American holdings in the Pacific. Two days after attacking Pearl Harbor, they seized Guam, and two weeks after that they captured Wake Island. Before 1941 came to a close, the Philippines came under attack.
