A. Jackson's attacks showed how weak Spain was in Florida is the correct alternative.
In 1818, Andrew Jackson's hunt for the Red Sticks ended up causing international affairs and diplomacy problems. This happened because the invaded land was Spain's territory and got invaded without any official cause or declarations of war.
Despite the controversy the invasion actually ended up turning Andrew Jackson into a hero and forced the signature of the Adams-Onís Treaty, in 1919. The treaty officially transferred the Florida region to the U.S. from Spanish domain. These events were important for this resolution because even though Spain was angered with the 1818 invasion, it showed their inability to retaliate or conquer back the land. Therefore, the only viable option was for the Spanish to sign the treaty and cede Florida, showing how fragile and unable to the defend the land by the Spanish, relinquishing their last piece of land in the Americas.
