Israel has completed preparations for an attack on Iran’s nuclear facilities and is ready to strike once President Donald Trump gives his approval, senior American and European diplomats told the New York Times on Wednesday.

Experienced U.S. and European officials expressed to the Times that the likelihood of an imminent Israeli strike on Iran is believed to be very high.

An Iranian official told the Times that Tehran has already devised plans for retaliatory strikes on Israel, should Jerusalem target the Islamic Republic’s nuclear assets.
