The United States has done much, since its founding, to earn the decent respect of mankind that the founders felt the country needed. But in directly asking foreign countries to mistrust us, Republicans are, it seems, intentionally trying to throw away what remains of this respect. It is hard to see how this could be good for the country.
While America's relationship with Israel is important, Chuck Hagel is being considered for Secretary of Defense of the United States, not Israel. Whether he would be good for Israel or not cannot be a central concern -- and certainly not the cause to preemptively slander and dismiss this decorated soldier.
