Just the oposite.
Iran is making themselves look bad to the world every time they hijack a tanker, or bomb fuel that hikes up energy costs. The more the US retrains itself from looking like a trigger happy aggressor looking for an excuse, but rather, a reasonable participant in geopolitical discourse, the worse things get for Iran
Like Bill Clinton did with Al Qaeda? Or like the approach Obama took to ISIS?
At some point, not acting is seen as weakness and the Iranians will use that to their advantage.
