I believe the answer would be France.
The United States bought 828,000 square miles of land from France in 1803. The French controlled this region from 1699 until 1762 when it became Spanish property because France gave it to Spain as a present, since they were allies. But under Napoleon Bonaparte, France revived the aspirations to build an empire in North America so the territory was taken back in 1800. However, those big plans were not meant to be because Napoleon needed to concentrate on preparations for war with the British Empire and so the land was sold to the United States. The price was 15 million dollars.
The purchased territory included the whole of today’s Arkansas, Iowa, Missouri, Kansas, Oklahoma, and Nebraska, parts of Minnesota and Louisiana west of Mississippi River, including New Orleans, big parts of North and northeastern New Mexico, South Dakota, northern Texas, some parts of Wyoming, Montana, and Colorado as well as portions of Canadian provinces Alberta and Saskatchewan.
The correct answer is “preserve life.”
<em>The Personal Recovery proficiency that defines Captivity Models of Prisoners of War, Peace Time Government Detention and Hostage Detention is “preserve life.”
</em>
When some element of the Department of Defense or a civilian is detained, missing or isolated in a military or foreign affairs operation, the government initiates a Personnel Recovery procedure under the supervision of the Joint Personnel Recovery Agency. The Personal Recovery proficiency that defines Captivity Models of Prisoners of War, Peace Time Government Detention and Hostage Detention is “preserve life”. Many of the times the government initiates diplomatic negotiations to bring the detained individuals back to its country of origin.
The constitution confers absolutely on the government of the Union, the powers of making war, and of making treaties (Treaties means "A formally concluded and ratified agreement between two countries.) Consequently, that government possesses the power or will of acquiring territory, either by conquest or treaty Marshall said. Hope this helps! if not please let me know
