Tehran’s leaders crafted a plan ahead of the current conflict that would escalate the fight across the region, and let the military keep battling even if its top commanders fell

Iran had for two years responded to foreign attacks with limited counterpunches directed at its attacker. Instead, under the new strategy, Tehran would escalate conflict across the region, especially hitting Arab Gulf states and hampering the global economy in hopes of dampening President Trump’s willingness to prolong the conflict and coming back for a future one.

That plan includes implementing its so-called mosaic defense, a decentralized approach that allows individual commanders the autonomy to keep up the fight if cut off from their superiors.

According to this article, Iran had advised its neighbors of its new strategy. But, apparently, the US believed otherwise.

The one quibble I have about this article is calling it a High-Risk strategy. As far as I can tell, that's its only viable strategy. Unless you want to call surrender a strategy.
