If it is the offical foreign policy of the United States to ensure the survival of the State of Israel, both now and in the future, then should it be expected as a sign of fairness to all the other nations of the world, that the United States also commits itself to ensure the survival of all nations, both now and in the future?

For example, say that in 10 years from now, all the nations that border the State of South Africa suddenly decide that South Africa needs to be wiped off the face of the Earth for one reason or another. If that was to occur, then the United States should automatically obligate itself to ensure that does not happen.

Or as another example, say that in 25 years from now, all the nations that border the State of Peru suddenly decide that Peru needs to be wiped off the face of the Earth for one reason or another. If that was to occur, then the United States should automatically obligate itself to ensure that does not happen.

Since the United States is obligated to the survival of the State of Israel, does this mean that it is also obligated to save all nations?
