Invasion

An invasion is a military offensive in which large parts of the armed forces of one geopolitical entity aggressively enter territory controlled by another such entity, generally with the objective of either conquering, liberating or re-establishing control or authority over a territory, forcing the partition of a country, altering the established government or gaining concessions from said government, or a combination thereof. An invasion can be the cause of a war, be a part of a larger strategy to end a war, or it can constitute an entire war in itself. Due to the large scale of the operations associated with invasions, they are usually strategic in planning and execution.

Famous quotes containing the word invasion:

    We should have an army so organized and so officered as to be capable in time of emergency, in cooperation with the National Militia, and under the provision of a proper national volunteer law, rapidly to expand into a force sufficient to resist all probable invasion from abroad and to furnish a respectable expeditionary force if necessary in the maintenance of our traditional American policy which bears the name of President Monroe.
    William Howard Taft (1857–1930)

    An invasion of armies can be resisted, but not the invasion of ideas.
    Victor Hugo (1802–1885)

    Every collectivist revolution rides in on a Trojan horse of “Emergency”. It was a tactic of Lenin, Hitler and Mussolini.... The invasion of New Deal Collectivism was introduced by this same Trojan horse.
