Think about imperialism in Iraq and Afghanistan, when the U.S. invaded to contain independent governments, obtain pockets of oil, and to reassert its self-mandated role in being world police. This is also an a example of interventionism, but you can use interventionism in the context of U.S. interventionism with the financial and trade sanctions on Iraq — which starved 500,000 children after the Iraqi government decided to encroach on Kuwaiti territory for a grip on oil pockets. For the other examples, you need to clarify if this is global or U.S. history.
