A conflict with Guyana will provide an excuse for American intervention to spank Venezuela. It's very likely that that is the plan, making Guyana a helpless pawn.
Strange how history plays. It was America who riled up the Venezuelans about the 1899 tribunal back in the days of the PPP communists. The intent to invade Guyana if the need arises. Now, with Venezuela's leftist leanings-the notion of America beating up Venezuela for Guyana. Guyana is strategic in the hemisphere.
I say, Venezuela should make their move and see how it pans out. Dey gat nothing to loose-either they get Essequibo or they don't. It is worth the little collateral damage.
Any move by Venezuela will get the US involved so they will lose.
