Seemingly, US unilateral withdrawal from the 2015 Iran nuclear deal and Washington's threats against Iran and its international economic and political engagements tend to constitute the most vital issues affecting Iran in recent months.
Despite the long history of US threats against Iran, a fresh wave of menaces, mainly the outcome of the radicalism now overwhelming the White House, is at its highest level.
Over the past 40 days, there have been many ups and downs in confrontation between Iran and the United States.
Now with US President Donald Trump and his team and with Washington staying out of the Iran deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), the face-off between Tehran and Washington has entered a very critical stage.
Trump and his administration, from the outset adopted a radical stance in their foreign policy while they spared no efforts to follow a unilateral approach towards Iran and other countries that are independent from the US and its policies.
They argue that they are going to guarantee the US interests through giving priority to the US economic interests over anything else.
In other words, they blatantly favor the US economic benefits over its international interests and they even sacrifice the US international credit to go on with their plans. That is why the US government considers the violation of international agreements like the JCPOA a legitimate move. Washington also snubs mistrust of the global community and turns a blind eye on demolition of its global credit or even the discontent of the American media or the elite in the country if trade interests and economic benefits of the capitalist segment of the society are secured.
Trump and his colleagues over the past year have clearly demonstrated that they have adopted a strategy of a head-on confrontation with the Islamic Republic of Iran as an independent nation and a country not aligned with the United States, using all its economic and diplomatic capacity to reach their goals.
But to address the US approach, what remains to be determining and decisive is the policy followed by Iran on its path towards protection of its authority and national coherence.
It has been proved during the past 40 years that whenever internal coherence, national unity and people's trust in the authorities have been at an acceptable level, foreign threats have failed to work.
And on the contrary, in the lack of such a trust and coherence, domestic dangers as well as foreign threats have tended to prevail.
