W/o help from countries like the US,UK or France, I don't think the Dutch would be able to do much about any invasion force.
The Dutch do not have any major force projection abilities and they would only be able to deploy De Zeven class frigates
These could Probably execute standoff attacks with Tomahawk IV LACMs taking out any Venezuelan Harbours/port facilities which serve as staging areas
for the invasion and occupation forces. They would need near real time sat-feed for effective strikes and I guess they could buy this?
Harpoon AShCMs would serve as a primary weapon against any Venezuelan naval blockade(Lupo class frigates).
The frigates would be threatened by Mirage III carrying AM-39 Exocet AShCMs, though I think the ships have good air defence capabilities withe near
future defence even against sea-skimming targets.
Now with the inclusion of the Su-30mk2 a/c, the Venezuelan AF gets a range of options for Anti-shipping from the Kh-59,Kh-35,Kh-31 and Kh-29.
I'm not sure which ones are actually being purchased by Venezuelan AF but with the Su-30Mk2 they have all the options and the real threat is
obviously the supersonic Kh-31.
This a/c would pose the greatest threat to the De Zeven class frigates.
Summarizing, if the Dutch are able to get there early and get a few good shots in, then maybe they can dissuade the Venezuelans with mounting
international pressure etc etc..
However if the Venezuelans are quite serious about the acquisition then they
will have more cards to play; and if the Dutch lose a Frigate then things will looking bad from them.
Will this face-off ever happen?
IMHO never, not in the current geo-political situation.
Will the US/UK help out if it happens?
hmm.. maybe the US will but whether overtly or covertly; I'm not sure..
definitely covertly with intel,sat-feed etc..
And bandit795, nobody wants war.. Not in a beautiful place like that..
