The warning came after US president Donald Trump threatened to strike Iran again if it did not accept a deal to end the conflict in the next few days.‌In a statement the IRGC - Iran’s most shadowy military organisation - said: “Should aggression against Iran be repeated, the regional war that was promised will this time extend beyond the region, and our crushing blows in places you can scarcely imagine will reduce you to ashes.” The military group added that despite attacks by “two of the most expensive armies in the world ” Iran has yet to use its complete strategic capacity.‌‌READ MORE: Ukraine gains upper hand in horror frontline battles against Russia as Zelensky plots more attacksREAD MORE: Horror in Lebanon worsens as Donald Trump puts 'full-scale' Iran attack on holdIt was referring to America and Israel ’s armed forces. The full IRGC statement said: “Although they attacked us with the full capabilities of two of the most expensive armies in the world, we did not deploy all the capacities of the Islamic Revolution against them.”Trump warned a new US attack would deal such a blow to Tehran that it would be a “big hit,” if Iran refuses to agree on a lasting deal to end the fighting. The threats exchanges followed a warning from US VIce President JD Vance who said allowing Iran to have a nuclear weapon would set off a dangerous atomic arms race.‌He said: “Iran cannot have a nuclear weapon,” before lauding US Armed Forces “degradation” of Iran’s military capabilities in weeks of war since March. He added Iran having a nuclear weapon would lead to other nations “scrambling” to get their own, setting off a “nuclear arms race” that would “make us all much less safe”.Vance said: “Iran would really be the first domino in what would set off a nuclear arms race all over the world.” On Tuesday Trump warned US attacks on Iran will resume in “two or three days” if Tehran’s regime does not give in to his demands.‌Major sticking points on any peace deal have complicated the negotiations as Iran wants Lebanon and Hezbollah to be included in any settlement.
