Protect the US against threats
To finish the Louisiana Purchase, Jefferson needed to set aside the principles that he upheld. This is because the transaction that he was about to deal with were not states in the constitution. If he waited for amendments, the deal would have failed. However, he received full support from the Americans, and he went through with the purchase deal.
He therefore needed to take quick action since he realized that Spain had also signed a secret treaty to cede with France. This is the reason why the French government threatened America.
The correct answer to the question above would be the last option, "in multiple countries all over the world." Terrorist attacks by fundamentalist groups have occurred in multiple countries all over the world. They have been doing recent terrorist attacks, one in Paris last year and Syria.
Is there answer choices to this?
