There is no easy answer to this question. There is no doubt that in the past things were easier for American Jews. They usually participated in fundraising in order to support the cultural and economic development in Israel regardless of the current political situation. But as the years went by, the situation changed.
The current policies of the Netanyahu government keep on raising a lot of ethical question marks. Current American Jews are mostly liberal although most of them still strongly support Israel. Nevertheless, the support that they offer is mixed with a lot of dismay and discontent.
The conflict keeps on growing although the current Israeli government doesn’t think that it is that significant. For instance, American Jews don’t serve in the Israeli army. They also don’t get to vote, which means that they are not part of the political life. However, if the new generation grows more distant, Israel will have to deal with the fact that it lost one of its strongest allies. Only time will tell the effect of such circumstances on the welfare of modern Israel.
