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.
However, the events in Pearl Harbor actually led to the escalation of World War II. The day after the attack, the United States declared war on Japan and so entered World War II. President Franklin Roosevelt in a speech to Congress stated that the bombing of Pearl Harbor was âa date which will live in infamyâ. Shortly afterwards, Germany also declared war on the United States.
