United Kingdom may rethink counterterrorism strategy

Significance

It was the first terrorist attack in London since the July 7, 2005 bombings, and the first attack subsequently claimed by Islamic State (IS) in the United Kingdom.

Impacts

• Security arrangements for Parliament will be strengthened; however, MPs will probably resist moves to limit the public's access.
• MI5 has initiated an internal inquiry into why it did not place the attacker under surveillance.
• Both the United Kingdom and the EU are interested in continued cooperation on counterterrorism after Brexit.
