John,The truth is, dispensationalists are far more likely than covenant theologians to actively support the nation of Israel.
I want to avoid casting aspersions on the goodwill of CT's or Dispensationalists as to their willingness to help those in need (unless you meant something different by your assertion), but you cannot deny that Dispensationalists have an eschatological dog in the hunt when it comes to Israel. John Hagee may be a few dispensations short of a Happy Meal, but he still represents a certain segment of Dispensationalism with his desire to help Jews return to the Holy Land in order to speed up the prophetic clock. That is one reason for Dispensationalists to actively support the nation of Israel.
