It is difficult to see what motivation Iran has to assassinate the Saudi ambassador to the US. The man was an advisor to the Saudi King, but is not a member of the Royal Family, so his loss may not be too painful. Iran has refrained from foreign terrorist acts for a good number of years, certainly in the last decade when terrorism became internationally unacceptable (since 9/11). Let the US prove its case publicly (in court) and under close examination of the facts. I only hope that we don't find that the charges are based on forged documents as the charges against Saddam were. If this happens, the question will be: Who has the motivation to forge such charges. Oops, better not to ask...
