While in the past the USA has played a good role in the redemption process, such as improving freedom and civil rights for oppressed Jews and helping them against the Nazis in World War II and in the vote to establish the state of Israel in the UN, in later years in many areas the USA has been more of a minus for Israel than a plus.
1 It pressures Israel to make suicidal peace deals
2 Gives more arms and aid to the Arab enemies than to Israel {better it give nothing to either side, or if they give to Israel, it should be as reparations for "peace deal damage" and not as aid}
3 It is a source for warped moral values, such as, homosexuality, etc.
4 Its irresponsible economic policies threaten to seriously damage the whole world economy
5 It encourages Israel to look to the USA as their savior as oppose to trying to solve the problems themselves and to depend on G-d.
Given these problems, would it be better for Israel to have, the USA split up to 50 separate countries, or do you believe, that a split USA might even be worse for Israel?
