The sanctions are specifically designed to prevent Syria from rebuilding

On Wednesday, the House passed a bill that prohibits the US from opening diplomatic relations with the Syrian government of Bashar al-Assad and expands harsh sanctions on Syria to prevent other countries from normalizing with Syria.

The Assad Regime Anti-Normalization Act passed in a vote of 389-32, demonstrating broad bipartisan support for the economic war against Syria. Only 28 Democrats and four Republicans voted against the bill. The legislation now heads to the Senate.
