What happens now that President Donald Trump has said he will move forward with tariffs on steel and aluminium products?

Analysts are warning of a trade war, as officials from Europe, Asia and Latin America threaten retaliation.

Mr Trump predicted it would be “easy” for the US to win.

But most economists and trade experts reject that view, saying every country, including the US, stands to lose in the event of a serious trade fight.

“If what we’re talking about is who gets hurt the least, that would probably be the United States, but all countries get hurt in a trade war,” says Edward Alden, senior fellow at the Council on Foreign Relations.

Here’s why “winning” might not be so easy for the US.

1. Tariffs may not actually boost steel and aluminium jobs much
2. Tariffs are likely to raise costs in the US
3. Tariffs could hurt allies and prompt retaliation
4. China has options
5. The domestic political consequences are unclear
