The doctrine is also pure propaganda. What does a non-martial mass murder by National Socialists have to do with a potential military attack by Iran? Jews who revere the memory of their murdered ancestors should be offended by Krauthammer's shameless attempt to make use of them this way.
Krauthammer's doctrine is a bald attempt at banking political backing for the continuation of the neocons' Jacobin foreign policy positions. As Vox points out, Israel would be singularly foolish to welcome such a doctrine.
This is worth noting. One of the reasons Vox gives for such an alliance being a bad idea is the following:
The next administration. It is possible that if he is elected president, B. Hussein Obama will be inclined to continue the positive relations that Israel has enjoyed with previous presidents of both parties. But given his obvious ties to African supremacists and third-world recrimination ideology, to say nothing of outright anti-Jewish supporters such as the Rev. Eric Lee, this is far from given. His middle name is not "Sadat," after all.
