A summary of the actions of the many aggressive regimes in Europe of the past several centuries would include mostly religious "holy" wars and a desire for territorial expansion.
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The reasons why Napoleon might have had for selling the Louisiana Territory to the United States could have been the following.
Experts agree on two basic reasons for French Emperor Napoleon decided to sell the huge Louisiana territory to the United States. The first reason, France needed a lot of money. It had deep debts as a result of many wars. Secondly, the Lousiana territory was immense and was too far away from France, so it was very difficult to defend.
These circumstances were an advantage to President Thomas Jefferson, who sent James Madison to help Robert Livingston (the Minister to France) in order to accelerate the negotiations to close the Louisiana Purchase in 1803.
During war time most male citizens are employed (If the waring country uses conscription) which lowers the national unemployment rate. Factories for non essential items will start to switch into making products for war use which makes businesses boom and grows the national economy. Also employment rates rise again due to the factory workforce hiring women and men who cant fight in war to work in the factories. War-bonds fund the government aswell, because citizens buy them in a way to "loan" their government to support the war effort which raises their military budget. The development of new technologies can also lead to economical prosperity.
A great example of this is the United States during the Great Depression when unemployment rates were at a all time high. Once Japan declared war on the United States, unemployment rates were back to normal due to conscription being implemented for male citizens. The females also worked in the factories creating munitions and arms for the war effort.
