The White House and CIA are likely to have been involved in the decision to warn Iran ahead of the deadly Jan. 3 suicide bombings. This indicates how serious the US was in both looking to save innocent lives as well as signaling an intended thaw in its mood towards Tehran. Yet Iran ignored the warning for reasons that are unclear. This continues a pattern of Iran rejecting the good faith shown by the US in recent times — including last year's deal to unfreeze $6B in Iranian money held in South Korea in exchange for the release of US-Iranian citizens.
Tehran is fighting a "war on terror" of its own. Exacerbated by simmering tensions caused by the Israel-Hamas war, this includes Israel's airstrike that killed five senior members of Iran's Revolutionary Guard Corps in Damascus on Jan. 20 or the Dec. 25 strike that killed Iranian general Seyed Razi Mousavi in the same city, as well as the recent flare-up with Pakistan. Iran faces so many enemies — including the Islamic State group and US hegemony — and is justified in being cautious about all the information it receives in a volatile threat environment.
