US President Donald Trump has denied any “infighting whatsoever” over Iran in his administration.

"There is no infighting whatsoever," he said on Twitter amid reports that he may dismiss his hawkish national security adviser, John Bolton in the wake of escalation of tensions with Tehran. "Different opinions are expressed and I make a decisive and final decision -- it is a very simple process."

The president, who has ordered a military buildup in the Persian Gulf and incessantly issues threats towards Tehran, also predicted that Iran will seek to negotiate with Washington soon.

"I'm sure that Iran will want to talk soon," claimed the US president.

On Tuesday, the British general overseeing the so-called US-led coalition forces in Syria and Iraq cast doubt on US concerns towards what it describes as “threats” from Iran.

British Major General Chris Ghika asserted that there has been “no increased threat from Iran,” a comment he refused to reassert and later dismissed by Washington.

The United States Central Command issued a statement saying Ghika’s assertion about Iran run “counter to the identified credible threats available to intelligence from US and allies regarding Iranian-backed forces in the region.”

Recent reports suggested the US planned to send more than 120,000 troops to the Middle East for a potential war with Iran.

Trump said on Tuesday the reports could be “fake” while insisting that he had no immediate plan for launching a war on Iran.

Meanwhile, lawmakers such as Vermont Senator Bernie Sanders are making efforts to make sure Trump cannot order war with Iran without permission from US Congress.

Iranian Defense Minister Brigadier General Amir Hatami said Wednesday that the Islamic Republic currently has the highest level of defense preparedness to counter any threat against the country.
