Which term best describes Theodore Roosevelt's "Big Stick" foreign policy?

Preventive intervention

Appeasement

Isolationism

Collective security

Preventive intervention

Explanation:

The US had proven to be able to wage a winning war against their enemies and had the most powerful navy at the time. Roosevelt's Big Stick policy relied on the American military force.

If any country at any time wanted to orchestrate whatever project that the US would not approve, it would be threatened. Roosevelt was aware that American domination was established by previous successes and shows of force, so it was expected that no country would permit itself a war with low chances of affording, let alone winning.
