Was Netanyahu and Boehner out of line?

The United States has been a long standing ally of Israel. However, was it purely political of PM Netanyahu to accept Congressman Boehner's invitation to address congress because of his reelection, or was it necessary because he truly believes the threat to Isreal is greater if the United States continues to support Iran in negotiations? Also note the break of diplomatic protocol. Basically both Isreal and congress not notifying the White House of Netanyahu's visit. Lastly, as silly as it may sound, but would this be considered using the open door policy?
