The father (and the court) may have valid reasons to suspect his wife's motives and plans. From the news story, it seems that the last time the ex-wife took the kid out of the country she was only supposed to go for a month, but then kept the child away from the father for 14 months. Plenty of American parents have completely lost contact with their kids when the other parent took them off to some foreign country and the American courts lost jurisdiction. Maybe Mr. Korn has good reason to fear that will happen with his daughter.
A two year old needs regular contact with BOTH parents. I don't know why the ex-wife in this case feels she has to move to Israel, but I think that for the child's welfare she should probably defer her move, at least until the child is a lot older.
