My personal belief is that the elections won't change anything as far as Israel is concerned. Israel must act alone and take her destiny in her own hands, whoever is President of the USA. In a way, it's even worse for Israel when Republicans are in charge in America because it gives most Israelis a spurious sense of security - just as it is even worse for Israel when the Likud is in charge rather than the left.
However, these elections are important for America and Americans. So I guess the decision depends on where JTF wants to focus its attention right now, on America or on Israel ?
