Israel and the United States are preparing for an imminent Iranian retaliatory strike against Israel this week, as the latter has placed its military on high alert, while U.S. officials have been working to prepare their military teams. An Iranian diplomat briefed by his government on the developments revealed that "efforts by various countries to convince Tehran not to escalate have been and continue to be futile in light of the recent Israeli attacks." The diplomat added, "There is no use in that. Israel has crossed all red lines. Our response will be fast and strong," as reported by the Wall Street Journal. Meanwhile, a U.S. official stated that the Biden administration is currently taking a cautious approach, with no indication that Iran has made a decision on whether to respond or how, and it is expected that any response is likely to occur within a few days to a week.
