Earlier quoted context omitted.
It could become wrong if they lose the support of the west. Imagine the US and EU giving up on Israel. It's a multi dimensional issue and playing nice with their neighbors may be advantageous if nobody knows (publicly). But if they do and there are bigger more important relationships (namely US) start to be put at risk, it could be the wrong move.
No chance, AIPAC, BICOM and various lobby groups ensure politicians are in the pockets of the Israel lobby. This isn't to say other countries don't have corrupt lobbying practices. But the unilateral multibillion dollar IDF funding raies questions.
There is also the chance of the US losing a lot of its power through various means (ie. Dollar losing reserve currency status, US military being tested by China and losing etc.). If this happens, they may be forced to cut Israel loose. Israel has no other solid allies and so they will flounder for a while but eventually sink because once the US is out others will be free to begin economic sanctions and the country cannot survive that indefinitely.
In both of these scenarios, the lobby groups become less effective and possibly get defeated. Long term we are moving towards a world where lobbies become less powerful. Its going to take decades though.
