Ironically it's very possible the support for US military intervention is higher among Venezuelans than US citizens.
On the plus side, that's probably good for the odds of success.
On the minus side, they're not paying the bill.
The question is whether it's the majority of Venezuelans. I have no doubt that there are many who hate Maduro and his regime - for very good reasons - but that's true of many authoritarian countries that nevertheless have the "silent majority" tacitly supporting their regime.
Do we know who's been installed as a replacement? As with Libya, getting rid of a bad leader doesn't necessarily make the situation better.
