Israeli Channel 12 has reported that Washington and Jerusalem coordinated a joint operation against Iranian targets that was planned for months, with the initial phase expected to run for four days. An unnamed Israeli security official told the channel that Israel is mounting the operation with full force and that the United States shares its position. The report says the first strikes were timed for morning hours to catch Tehran off guard, a tactical departure from the more common preference for nighttime raids.
The timing and duration the channel described are notable because they signal an intent to seize the initiative and impose an operational tempo that could overwhelm Iranian short-term responses. The report also quotes United States President Donald Trump expressing frustration at recent US Iran diplomacy, reiterating that Iran must not acquire nuclear weapons or uranium enrichment capability and saying that sometimes force is necessary. Those remarks underscore the political context in which any kinetic action would be framed by Washington.
If accurate, a US aligned, months-long campaign planned with Israeli forces would mark a significant intensification of preventive and punitive options aimed at Iran. The stated choice of daytime strikes is tactically striking; attacking in daylight increases the likelihood of surprise only if Tehran does not expect an assault at that hour, but it also raises the probability of detection, collateral damage and international scrutiny. The use of anonymous security sources in the Channel 12 report leaves open crucial questions about the scale, targets and legal rationale for any operation.
Operationally, planners may have judged that a concentrated initial window of activity over several days is necessary to achieve discrete objectives before Iranian air defenses or regional proxies can respond. But any kinetic campaign risks rapid escalation. Iran has a range of asymmetric response options, from proxy attacks across the Levant and Iraq to strikes on commercial shipping in the Gulf and cyber or missile responses of its own, each of which could broaden the conflict and draw in other regional actors.
The diplomatic implications are immediate. A coordinated US Israeli operation would complicate ongoing and potential future negotiations over Tehran's nuclear programme, alienate European mediators who favour restraint and could trigger debates in capitals about the legality of preemptive strikes. For neighbouring states and global markets, the prospect of an expanded confrontation would raise energy security concerns and force allied governments to choose between tacit support, public condemnation or calls for deescalation.
For now the details remain fluid. The Channel 12 account has not been independently corroborated and the identity of the anonymous security official was not disclosed, leaving open whether the broadcast reflects operational truth, deliberate signaling to Tehran, or a mix of both. Nonetheless the combination of months of planning, US alignment and a stated aim to exploit the element of surprise gives this report significance beyond the immediate tactical claims: it reveals how Israel and the United States might be prepared to combine military pressure with political messaging to shape Iran's choices.
