Iran and seige strategy. Will Iran provoke a land invasion?

Iran's best strategy seems to hunker down for a seige, blow up key oil/water infrastructure in the middle east, try to keep the Strait locked down and wait for the world economy drop. Trump may try to declare victory and leave before that, but Iran may think it wants to shame/defeat Trump and keep the seige going. This could actually provoke trump to do a land invasion as the economy falls. Does Iran want de-escalation or do they want trump to be defeated? They may prolong things to ruin trump, in a pyric victory. Trump wants the leardership gone, so its all or nothing for Iran's leadership.
