Netanyahu, the Constitution, and Public Opinion

Alan Dershowitz writes at The Wall Street Journal:

As a liberal Democrat who twice campaigned for President Barack Obama , I am appalled that some Democratic members of Congress are planning to boycott the speech of Israeli Prime Minister Benjamin Netanyahu on March 3 to a joint session of Congress. At bottom, this controversy is not mainly about protocol and politics—it is about the constitutional system of checks and balances and the separation of powers.

Under the Constitution, the executive and legislative branches share responsibility for making and implementing important foreign-policy decisions. Congress has a critical role to play in scrutinizing the decisions of the president when these decisions involve national security, relationships with allies and the threat of nuclear proliferation.

Congress has every right to invite, even over the president’s strong objection, any world leader or international expert who can assist its members in formulating appropriate responses to the current deal being considered with Iran regarding its nuclear-weapons program. Indeed, it is the responsibility of every member of Congress to listen to Prime Minister Netanyahu, who probably knows more about this issue than any world leader, because it threatens the very existence of the nation state of the Jewish people.

Gallup reports:

Even as relations between the leaders of Israel and the United States reportedly deteriorate over disagreement about how to handle Iran's nuclear program, Israel has retained its broadly favorable image in the U.S. over the past year. Seventy percent of Americans now view that country favorably, and 62% say they sympathize more with the Israelis than the Palestinians in the Mideast conflict. By contrast, 17% currently view the Palestinian Authority favorably, and 16% sympathize more with the Palestinians.

...
A key reason Americans' sympathy for Israel has solidified at a sizable majority level is that Republicans' support for the Jewish state has increased considerably, rising from 53% in 2000 to more than 80% since 2014 -- with just 7% choosing the Palestinian Authority. A particularly large jump in GOP sympathy for Israel occurred in the first few years after 9/11 and at the start of the 2003 Iraq War.

Democrats' support for Israel has also risen since 2000, but not quite as sharply as Republicans'. Additionally, the percentage of Democrats sympathizing with Israel fell 10 points this year to 48%, possibly reflecting the tension between Obama and Netanyahu.
