It would be absolutely foolish for Iran to give up Nuclear enrichment. All that Hard Work to be dismantled, and no guarantee that they won't attack you once they have defanged you.
Both Iraq and Libya were attacked after they gave up their nuclear programs.
If anything I think Iran should be building more facilities deep deep underneath mountains, and buying S-400s, Beriev A-100s, Su-35s and further deepening their air defenses.
Sanctions don't mean anything especially when the Emergence of China and the Breakoff of Russia from the West is diminishing their potential. If Iran is able to hang on a bit longer, that Sanctions hegemony is going to collapse on its own with China's growth/markets. The US cannot stay in the Middle East Long Term anyways, its pivoting towards the East Asia confrontation. Its already withdrawing from Europe. Iran just needs time and patience.
Russian expedition in Ukraine was a disaster. It
was assumed that Russia would overwhelm Eastern Europe but Russian advances are checked in Ukraine and Russian economy have also
taken a hit due to sanctions. Trump was scolding Zelensky in public but
made a deal with Ukraine. Russia is now under pressure to negotiate with Ukraine. American pivot to the Pacific is but a pressure tactic on China to keep it at bay there with support of Japan and Australia but the US is also in talks with China while South Korea is developing
sophisticated military capability to check North Korea. The US have no plan to shut down CENTCOM. The US have a strategic footprint in the Middle East via Israel, Qatar and Kuwait. Iraq and Syria were subjected to regime change in succession. Israel have destroyed Gaza and
virtually crippled Hezbollah in Lebanon and Syria with American support. Trump administration have made new deals with the GCC and in talks with Iran. The Middle East is being reshaped to the tune of the Abraham Accords and to facilitate
IMEC.
The Houthi have reportedly agreed to not attack ships in Red Sea. The Houthi can attack Israel but cannot stop it in its tracks and facing counter-attacks. Iranian options are now limited because Iran has lost ground in Syria. China have massive levels of trade with the WEST and Chinese companies are not immune to sanctions.
Iran now have difficult choices: To continue on the path as per your suggestion (or) negotiate a different outcome. It is a gambit in either case. One of these choices might turn out to be the best course for Iran. Which is it? Nobody have the crystal ball, right? My guess is to find a way to appease Trump.
Trump's strategic gameplay is stunning and have put many on the backfoot. Many were mocking him initially in all platforms but now finding out the hard way that his game is above their paygrade.
As for the kinetic options, the US also have
strategic bunker busters to destroy anything underground.
Chinese research also admits such possibility. This option might not be considered but underground facilities have been destroyed or rendered useless with strictly conventional payload in different wars. It comes down to "mission planning." Let's not be in hubris.
