Regarding David Ignatius's Dec. 27 op-ed, "We shouldn't ignore Iran's cyberthreat":

Perhaps if the United States would stop its cyberthreats (as mentioned in Mr. Ignatius's column), then Iran would follow suit. 

There are many instances in which the United States infringes on other countries' rights and then is shocked and offended if there is retaliation. Iran has as much right to use cyberthreats and to have a nuclear capability as do the United States and Israel.
