When President Trump suggested that Iran's borders might look different after the war, the statement landed inside Iran with the force of a "two-ton rock" - but instead of breaking the population's will, it drove even regime opponents toward the flag, political scientist Vali Nasr has told Bloomberg.

Trump's rhetoric about arming the Kurds and questioning Iran's territorial integrity crossed a line that separates opposition to the regime from opposition to Iran's existence, "Hvylya" reports, citing Nasr's interview on the Mishal Husain Show. "When President Trump talks about arming the Kurds, or that Iran's borders may not be the same at the end of this war, he's threatening Iran itself," Nasr said.

The threat taps into Iran's deepest historical anxieties. The country has spent 200 years watching aggressive neighbors and colonial powers chip away at its territory - Russia, the Ottoman Empire, Britain, France. Two world wars brought famine and occupation. The 1953 CIA-MI6 coup against Prime Minister Mosaddegh remains a defining trauma. Iran's revolutionary leaders built the Islamic Republic explicitly to end this cycle. "The Islamic Republic is the first government in Iran in over 200 years to give Iran genuine sovereignty and protect its borders," Iran's former foreign minister told Foreign Policy magazine, as Nasr cited.

The scenario is not hypothetical. If the state collapses and security forces cannot control a country the size of Western Europe, separatist movements among Kurds along the Iraqi border and Baloch along the Pakistani border - potentially backed by the US and Israel - could redraw the map. Nasr acknowledged the possibility but stressed that the mere talk of it has produced the opposite of its intended effect.

"It created a huge amount of anxiety, and rallying, if you would, to the flag," Nasr said. Iranians who might welcome the fall of the Islamic Republic are not willing to accept the dismemberment of their country as the price. Trump's dual-outcome strategy fails to account for a population that refuses to play the role Washington assigned it. The spiral risks of this miscalculation extend well beyond Iran's borders.
