Was Iran responsible for the CW atrocity in Halabja?
The question therefore arises whether the United States may have been politically motivated to place the main responsibility for Halabja with Iran. The allegation came as Washington was visibly tilting towards Iraq. Soon after the US State Department blamed Iran for the events, US officials were quoted as saying that the finding undermined the propaganda advantage Iran was seeking by publicising the attacks.
From this angle, the US assertion might be viewed as an attempt to undermine the moral high ground regarding chemical warfare Iran desperately tried to maintain during the war. The statement, however, may also have been motivated by politics in the UN Security Council. Since the end of 1987 the United States had been unsuccessfully pressing for a resolution imposing an arms embargo against Iran for refusing a cease-fire. While the permanent members remained divided, an opportunity for unity on the issue presented itself just before the Halabja attack. With Iran in the clear position of the victim of Iraqi violations of international law, the chances for success evaporated fast. Blaming Iran for the attack could then conceivably have been a manoeuvre to save the resolution.
