You may think they are idiots ....
My comment about them being "idiots" is sarcasm.
Some in that group are on the scent , others are in know. They stand for something and that seems admirable.
The link describes European banks (France, Spain, England, etc.) depositing (they have new money from the US and others and want to earn interest on it safely, short term, until they can decide on a better investment instead of having it sit there idly) their money with the ECB at a low interest rate instead of with each other at a higher interest rate. This is because they fear the other banks may be insolvent and could go bust overnight. Many predict a major European bank failure in the next few months.
How the US is connected is because large US banks hold european sovereign (Italy, Greece, Spain, etc.) bonds (debt) that may not be paid back. If that happens, the European problem spreads. The US does not want that, so they lend overseas to keep things afloat. The ECB cannot (by their charter; or whatever it is called) print money: the US can. The US lends (prints) money because the E. banks need to re-capitalize (increase their cash holdings). Since things are so bad over there, many don't trust the banks and other stuff and the banks cannot raise capital. So, in the form of currency swaps, the US re-capitalizes the banks. It's a form of QE.
QE is like this: prior to QE their are 10,000 people with your skills who can demand a certain wage. After QE, the money (your tax dollars or what is added to the national debt) which was used to train these additional people, there is 20,000 people who have your skills and compete with you. As a result, your wage decreases 50% because your field was already saturated. Your boss cans you, and hires a person who will accept a lower wage. He (part of a larger institution) is given a bonus for his business acumen (political influence - ability to encourage the use of tax dollars, or print money, to train more employees with the skills he/she needs). He has more money, you and the new hire have less.
I'm not an expert, but this should be pretty close.
