The Israel Lobby co-author Stephen Walt has a few helpful tips for the Obama administration in pressuring Israel to improve its behaviour. Such as:
In the past, the United States has often pressed other states to upgrade their own ties with Israel.… If pressure is needed, however, the United States could try a different tack.… For example, we could quietly encourage the EU not to upgrade its relations with Israel until it had agreed to end the occupation.
Many of Walt’s suggestions are very much of the softly-softly approach but alas this is the way in which international diplomacy seems to work.
If America doesn’t get tough on Israel, nobody else will in the West, including Australia.
