Doves clashed with police and the National Guard in August 1968, when antiwar demonstrators flocked to the Democratic National Convention in Chicago to prevent the nomination of a prowar candidate.
The US is pushing for even more harsh trade sanctions on N Korea ‘and those who trade with North Korea,’ which would include China.

The second half of the 20th century also witnessed a strong anti-war presence in other art forms, including anti-war music such as " Eve of Destruction " and One Tin Soldier and films such as M*A*S*H and Die Brücke , opposing the Cold War in general, or specific conflicts such as the Vietnam War . The current American war in Iraq has also generated significant artistic anti-war works, including filmmaker Michael Moore 's Fahrenheit 9/11 , which holds the box-office record for documentary films, and Canadian musician Neil Young 's 2006 album Living with War .
