Potential presidential candidate Russ Feingold says that voter unrest over the war in Iraq has elevated foreign policy issues to a rare level of importance.
The Wisconsin senator also told an audience in Platteville that Israel has a right to defend itself amid rising tensions in the region.
Israel has launched an offensive against Lebanon after guerillas captured two Israeli soldiers.
Feingold says he hopes Israel exercises restraint -- but he says the country has the right and the responsibility to defend itself from terrorists.
He opened his second swing through Iowa with a heavy schedule of events including a stop in Dubuque.
They included meetings with activists and fund-raising for candidates.
Feingold has been among the harshest critics of the war in Iraq and has urged a pullout of troops.
