U.S. and Israel step up attacks on Iran amid escalating tensions

The United States and Israel have stepped up attacks on Iran after U.S. President Donald Trump threatened to bring the country "back to the Stone Age," with Tehran warning of broader and more severe retaliation. The U.S. president says the country is close to completing its objectives without providing a clear timeline for an end to the conflict. Meanwhile, the global economy has shifted since the White House launched its trade war last April.
