To the casual observer, it appears the United States is pursuing a gradual and consistent approach:
First: Striking nuclear facilities and capabilities.
Second: Targeting and assassinating first, second, and even third-tier leaders to weaken decision-making and leadership centers.
Third: Imposing sanctions and economic pressure to weaken the state from within.
Ultimately, we might reach the most difficult option: direct intervention or a ground invasion.
The Americans are generally not hasty in their approach to results and have a long-term perspective on managing conflicts. Therefore, things may seem calm at first, but if we consider these steps together, we might see a strategy unfolding gradually and cautiously to achieve the ultimate goal.
