I don't believe they could have. In order to accomplish what they did, they needed full control of the situation, without fun control, they would not have made things better for their kingdom.
In the course of American history we have employed many tactics and ploys to keep our nation and our nation's beliefs safe. Isolationism, Imperialism, and Intervention all come into play at least once during each of the wars our country has fought in.
Isolationism: it's basically a policy of remaining apart from the affairs or interests of other groups to prevent unnecessary wars. It mostly involves politics rather than trade.
The most prominent example of American Isolationist Policies is during WWII, when Isolationists advocated non-involvement in European and Asian conflicts and non-entanglement in international politics. This kept America out of WWII until the Japan`s attack on Pearl Harbor in 1941 which brought the United States into the war on the Allied side.
Next up is Imperialism: it is another policy, only it involves extending a country's power and influence through diplomacy or military force. It mainly influences our economy and it also helps to keep the peace between the weaker nations.
U.S. imperialism took many different forms in the 20th century, ranging from colonies in Puerto Rico and the Philippines to protectorates in Cuba, Panama, and other countries in Latin America, and open door policies such as that in China. Formal colonies would be ruled with U.S.-appointed colonial governors and supported by U.S. troops. During WWII the Japanese attacked the american colonies in the Philippines and drove the United States out. The General McArthur declared as he was evacuated from the Philippines that" I shall return" and he did.
And last but certainly not least Intervention: interference by a country in another's affairs to improve a situation. Mainly to help maintain order and to stop dictators.
The best examples of this are immediately after WWII and it was called the Cold War foreign policy. The United States and its allies used it to prevent the spread of communism as much as possible without starting a war with the Soviet Union aka: Russia. Vietnam was really just a battle of democracy vs communism.
Hopefully this answer should help you
In general, this statement is true, since throughout history many colonies have been used for this purpose, although there are many other reasons colonies are formed, such as to escape religious persecution.
The power to wage war within the constitutional system of the United States is only one aspect of the tension between the President and Congress. Both fight to expand their influence on the political conduct of the country. In this matter, the Constitution is vague and its interpretation has caused some conflicts; however, the political regime that she consecrates gives the President more expeditious mechanisms and flexibility to make their influence prevail in front of Congress.
The president of the United States "has the constitutional power not only to counterattack against any person, organization or State suspected of being involved in terrorist attacks against the United States, but also against foreign States suspected of hosting or supporting those organizations." It is a "constitutional power", which was "collected by Congress" as "inherent to the Executive" on September 14, 2001, just three days after the 9/11 attacks. This is possible without requesting authorization from the congress. As happened when Barak Obama, in March 2011, ordered to bomb Libya.
It is true that Section Eight of Article One of the Constitution specifies that the Congress (formed by the Senate and the House of Representatives) will have, among other powers, the "declare war (...) and adopt rules concerning to the capture of lands and waters ". But it is also true that the text does not specify what a "war" is. For this reason, some other conflicts are considered "military confrontations", but have been authorized by Congress, such as Vietnam, the Gulf War, the invasion of Iraq and the Afghanistan War.
