Any Israeli campaign on Iran without the U.S. support will face severe limitations given the long distance between the two countries.

The US has obtained new intelligence suggesting that Israel is making preparations to strike Iranian nuclear facilities, even as the Trump administration has been pursuing a diplomatic deal with Tehran,

WASHINGTON (AP) — President Donald Trump on Monday appeared to undercut a proposal that was offered by his special envoy to Iran, saying he will insist that Tehran fully dismantle its nuclear enrichment program as part of any deal to ease crushing sanctions.

Iran’s nuclear facilities are deep underground and heavily fortified. An effective attack by Israel would require U.S. assistance for both mid-air refueling and munitions, according to the February intelligence report.

Israel strike on Iranian nuclear facilities may be closer than expected, as new US intelligence suggests growing Israeli preparations. This comes while the Trump administration is still pushing for a nuclear deal with Iran.

New report reveals Israel may be preparing a strike on Iran's nuclear facilities following U.S. intelligence showing increased military activity.

Iran warned it would take action against Israel and hold the US “legally responsible” if the Jewish state acts on reported plans to attack the Islamic Republic’s nuclear facilities.

Alarmed at the prospect of further instability in the region, Saudi Arabia's 89-year-old King Salman bin Abdulaziz dispatched his son, Prince Khalid bin Salman, with the warning destined for Iran's Supreme Leader Ayatollah Ali Khamenei, according to Gulf sources close to government circles and two Iranian officials.
