The whipsaw chain of events involving Iran, Israel and the United States that culminated in a surprise ceasefire has raised many questions about how the Trump administration will approach the Middle East going forward.

The U.S. Department of Homeland Security warned Americans of a "heightened threat environment" on June 22 that could include attacks on U.S. soil. That fear appeared to dissipate when Iran attacked a United States military base in Qatar June 23, injuring no one.

President Donald Trump compared the American airstrikes on Iranian nuclear facilities to the only use of atomic weapons in warfare during the 20th century.
