United States Spying on Israel Post NSA Leaks

Following the 2012 and 2013 leaks by Wikileaks that exposed the US's surveillance of foreign heads of states and governments, the US stated that they would cease surveillance, or "spying", on foreign governments. However, recent discoveries have proven otherwise. Of course, with most generalizing statements, there were exceptions. One of which was Israel. 

Recently, news has come out of the US's continued surveillance of Israel, causing tensions between tensions to rise once between Conservatives and the current administration. It's not clear exactly how much information has been taken compared to pre- Wikileaks levels, but nonetheless "spying" has not ceased.  

This has led to criticism of the current administration by Republican candidates for the 2016 presidential race. Candidate Carson has said, “once again, (Hillary) has shown that her experience in government is merely an indication that she is unfit to lead," citing her time as Obama's former Head of State, and explaining "No doubt President Obama's former Secretary of State Hillary Clinton knew of the administration's spying efforts on Israel. It is shameful that she participated in undermining the U.S.-Israeli relationship."

The presidential race on 2016 will be one of even more polarized politics than seen in much of elections before. Carson is taking a firm stance against the spying of our "only ally in the Middle East". At the same time, one has to realize that in the interest of national security, spying is an integral part of acquiring intelligence. 

Questions:
1. Do you think that the US needs to stop all their surveillance of other nations and heads of state completely, and would it impact our national security, or would it have no real effect?

2. How will this event affect candidates for the 2016 election, and is this issue important enough to change the opinions of Americans enough to make an impact?

3. What is the limit when it comes to NSA eavesdropping and spying? Is there a common ground other than cessation completely?
