Historically the most dangerous tool of the US empire has been internal coups, but that has conclusively been defeated by Venezuela
As a result the US is grudgingly resorting to some bungled military attempt, likely a bigger version of that merc invasion several years ago, that was defeated by local fishermen
Aside from a few exceptions, US military invasions fail when targeting large countries; the jungles of southern and eastern Venezuela are impervious to US power projection, the Colombian border (which is only viable route to invade Venezuela) is closed and the northern coast is protected by a massive mountain range and dense, large, pro regime cities and towns
As a result the US will be forced to rely on air power and naval bombardment to damage the the revolutionary state
The logistical equation is fairly obvious in this case, it would require a decade of sustained warfare with the deployment of hundreds of thousands of troops to overcome the militia networks and the sheer geography of Venezuela
And the first dead Venezuelan child by a US bomb or bullet will gureentee the long overdue obliteration of the opposition for generations
They’re not going to go for a full invasion like that. It’s going to look more like Afghanistan.
They’ll decapitate the government and anyone further down the chain that they need to, then they’ll support the pro-US opposition. They won’t want to fully takeover or occupy.
The most they’ll do is set up some bases. Those bases will be impossible to remove because attacking them without getting airstriked won’t be possible. You can fire some rockets into them but that’s about it.
Those bases will then be used as HQs for clandestine operations locally to support the pro-US factions.
All they have to do to achieve this is decapitate the existing government and then set about supporting the opposition. It will fail in the longterm, just as it did in Afghanistan, but in the short term it will look like a success.
It all hinges on the decapitation strikes though. If Maduro and his government aren’t killed then it will be much much harder.
