Step 1: Read the cartoon:
Two armed US soldiers stand over a man sitting in ruins. The speech says: Now that we have destroyed your country, you can pay us to rebuild it. They add that they accept natural resources, like oil, as payment.
Step 2: Recall the event:
The USA led an invasion of Iraq in 2003 and removed Saddam Hussein. Iraq has some of the largest oil reserves in the world, and the cartoon shows the link between the war and oil.
Step 3: Check the options:
(A) Iraq: correct, this was the Gulf country invaded. (B) Saudi Arabia: not invaded, it is an ally of the US. (C) Kuwait: it was invaded by Iraq in 1990, and the US led the coalition that freed it. (D) Iran: not invaded by the US in this way.
Final Answer:
The Gulf country invaded by the USA was Iraq. This is option (A).
