The IRGC is 125k-150k people. Many of them are pot committed to the current government, because the IRGC has done... unforgivable things that a new government would be likely to punish.
Venezuela is also run by the same security apparatus and government as it was before. We didn't attempt to turn over the entire government.
thats in a scenario with soldiers pushing into no mans land under permanent drone control. Israel demonstrates much lower stats when enemy hides underground. I would imagine having no boots on the ground will lower the numbers further.
Venezuela wasn’t a regime change war it was a US-backed palace coup that left the entire regime except for the guy at its head in place in exchange for a narrow set of policy favors to the US.
It has little in common with Iran, which is more like the 2003 Iraq war (but, so far, without committing ground troops, but there is no way to maintain that with Trump’s stated goal of “unconditional surrender”; that’s going to require a ground forces occupation at a minimum, and probably a ground forces invasion to acheive it) than it is like the recent intervention in Venezuela.
Even if they are not particular fond of the regime that is in the process of being destroyed, the Iranian people are likely to resist that, just as occurred in Iraq (with the most significant resistance there coming from forces that were opposed to Saddam’s regime and which had been actively suppressed by it while it was in power.)
Maduro was such a bad leader that his prime minister sold him to the US.
Which means now Venezuela is still a chavist regime, but not under US embargo anymore. This will improve their economy a great deal, and if the regime doesn't capture all the profits for itself, will also improve the QOL of all Venezuelians, hopefully.
