You got me wrong. I was not talking about Polish pragmatism, I was speaking about the pragmatism of western nations in the late 30ties that had to be paid by the Poles because they trusted into a backing (i.e. by France or England) that was not there. De facto the Poles never had real allies. They were always alone.
You are wrong. Only Democratic Party administrations are “pragmatic”, just like Roosevelt in Yalta. Republican Presidents of the USA are full of honor and dignity and never betray their allies and friends.
That might be true but does not help you in your strategic situation. The problem with election-based systems like the US is, that after 4 or 5 years you have to deal with political change. Just take a look to Iraq. A operation that was started with much energy. Now the hard work has to be done and in America we are going to face the change to a new president. Now it would take even more stubbornness, patience, blood and money to win. BUT... ...if this new president is democratic and female she will surrender and the Iranians are going to take over because it is convenient. That means the sacrifice of all those fallen women and men is somehow senseless. Not to speak about all those decent Iraqis who will hang on the gallows for collaboration with the great "satan".
It happened already in Viet Nam and it can happen in Iraq soon.
What I want to say is that you can not trust in security matters into a superpower that is subject to permanent change only. We Germans have a bonmot: "Help yourself and God will help you". Therefore all decisions have to be done with responsibillity and brains. Acting on instinct/heart because of a pretended strength might be understandable but could lead straight into a disaster.
