Is us and isreali speculation about the iranian uranium enrichment prgram irresonsible considering recent "official" contradictions?   stance: yes:
Of course it is. I would compare the situation with the lead up to the Iraq war. There are those in government who are making accusations and then trying to build intelligence around those accusations. What is supposed to be done is to assess the intelligence first and come to your conclusions based on the intelligence.
Israel and the U.S. have a very unhealthy and dysfunctional relationship. We have helped Israel become a nation that relies on terror and violence against opposition instead of balancing strength with diplomacy.
Well if Israel decided to preemptively attack Iran unjustly you can bet there will be blind support from the U.S. government. This revelation should show people how dangerous all our speculative accusations are.
