here is all there is needed to know about the greece situation:
on one hand the greeks are a proud and independent people, the cradle of democracy and civilization. while they stand unashamedly with their other hand out begging for assistance. they cannot live within their means but it is not fair to treat them poor even though they are poor and depend on others to finance their bills and it is inhumane to just the throw bums out on the street. also, if they are thrown out on the street they will quit paying even a portion of the interest on their loans, so there are still a few pennies left yet to squeeze out of them, and bankers love squeezing.pennies.out of folks, it's their job.
here is the mexican standoff part: the bankers have to have conditions where they can squeeze out a few pennies so austerity must happen, the greek politicians cannot throw the greek people under the austerity bus anymore without losing their jobs and pennies, and the greek people will not vote to leave the euro because they know they cannot afford it on their own without free eurozone pennies.
greece will be brought to its knees and taught a lesson you lazy insolent jerks, but they will get some more pennies in exchange for even more austerity, after they kneel. you don't kill a country with commandos anymore, you kill them with kroner. kroner by the way is derived from kronos (time) and the interest clock on debt never stops ticking, time really is money.
this will all pass and a new arrangement for servicing debt will be reached sooner or later, because that keep the interest payment pennies rolling in and you still got the gloved fist principal balance clamped tightly on their neck (yay bankers!).
the only drama here is how much drama will happen before the inevitable solution? the greek people must yield to austery or perish, easy choice when atm's are empty. it won't be the politicians fault because it was the greek people that voted for the referendum. and the bankers still get to squeeze pennies, that makes them happy.
the question then becomes 'how can i time and play this chaos to squeeze a few extra pennies for my tsp account?' that is the game here. watch and see. it is an old story.
if you are a bankwalker, the day to get in is thursday. then forget about it until monday and see if the jackpot hit or if you lost your bet. the only potential hitch in the git along is what the people will do, when you put folks under pressure like that they become unpredictable and irrational, and bankers hate unpredictability. high times and high crimes, there is a lot of money at stake, good luck, may you always hit on the river.
