A top Iranian military commander has warned the United States against adverse consequences of a new military attack on the region, saying the move would be costly for the US. Any new military move by the US in the region will impose heavy costs on the country far greater than the costs it paid in Iraq and Afghanistan, IRNA quoted Deputy Commander of the Iranian Army's Ground Forces Brigadier General Kioumars Heidari as saying. The US should know that the Islamic awakening developed among regional nations has left no room for bullying and arrogance, he added. The situation in the Middle East and across the world has changed. No nation will yield to US bullying, the senior Iranian commander reiterated. Heidari also pointed to Iran's defense capabilities and said the steadfast and influential' Iranian Army's Ground Forces have gained valuable experiences over the past three decades and has the potential to defend the country. Amid the West's standoff with Iran over its nuclear program, both Tel Aviv and Washington have repeatedly threatened Tehran with the "option" of a military strike. They justify the saber-rattling by repeating allegations that Iran's nuclear work may consist of a covert military agenda -- claims the Islamic Republic has strongly rejected. Iran says its nuclear program is completely peaceful and within the framework of the Nuclear Non-Proliferation Treaty, to which it is a signatory.
