33440-472: The outbreak of the Korean War and at the urging of the National Guard, Congress reauthorized the separate state military forces for a time period of two years. These state military forces were authorized military training at federal expense, as well as "arms, ammunition, clothing, and equipment," as deemed necessary by the Secretary of the Army .

Nearly every state has laws authorizing state defense forces, and 19 states, plus the Commonwealth of Puerto Rico , have active forces with different levels of activity, support, and strength.

36993-447: The start or prelude to World War II. The exact date of the war's end also is not universally agreed upon.

(While the National Guard is operated by the states, most of their equipment and funding comes from
39501-421: The valuable capabilities that State Defense Forces can provide." In the decade following that article, however, no significant action has been taken on the recommendation.

39919-443: The volunteers were "saving money to buy a tank." With the end of the Cold War came a general decrease of interest in state defense forces. The September 11 attacks , however, generated additional attention and, with it, greater scrutiny from some in the United States military who questioned the training and equipment of the units and whether they provided an outlet for "warrior wannabes" who would not otherwise qualify for service in
40128-407: The war were not fulfilled in the peace settlement. From 1922 to 1925, the Fascist movement led by Benito Mussolini seized power in Italy with a nationalist, totalitarian , and class collaborationist agenda that abolished representative democracy, repressed socialist, left-wing, and liberal forces, and pursued an aggressive expansionist foreign policy aimed at making Italy a world power, promising

43054-404: Was elected the country's first president under the Constitution, and the Bill of Rights was adopted in 1791 to allay skeptics' concerns about the power of the more centralized government.

43263-403: Was postponed until the spring of 1940 due to bad weather.
