That is a really excellent question Monkt. I would guess that like most secret orders, they don't just have ONE grand strategy but several, all leading to their ultimate goal. A chess master doesn't either. He waits for the right time and puts plan B or C into effect depending on how his opponent moves his pieces. Effectively, they have lost the north american union, but that doesn't mean that they can't try destablizing some other part of the world when they consider the time to be right.
I would suggest first that Freemasonry is NOT a secret order. It is very visible and obvious to everyone. You will see our Square and Compass everywhere, at least in the USA.
Second, considering some of the big backers of the Revolutions were Masons, Sam Adams for one, Franklin. Washington and several others. 9 of the 56 Signers of the Declaration were Masons, as well as Ellery, Hancock and Hues.
The Tea Party, depending on who you talk to, was organized and played out primarily if not completely by Masons.
From my decades as a Mason and centuries for my Family being in Masonry, except for the oddball liberal, Masons tend to be more Libertarian in their beliefs politically. There are some bad apples, I have actually excused myself from a Lodge when I found out the members were KKK. Not something I could understand anymore than I could understand a Catholic supporting birth control.
If you actually have an open mind and want some reading material, I can supply a few sites that explain some of the conspiracy idiocies.
The other reason I think there are so many conspiracies about the Masons is that most people truly cannot believe that someone and some organization could actually be as good and giving as the Masons are.
With all that said, there are several Masons I have met over the years that if I had my way would not be allowed in Lodge ever again. I do not always have the ability to push things like this and I wont deny there have been and still are some idiots out there who are unfortunately still Masons.
