So interest on their money isn't their money too? Is that what you are trying to say?
I have read what Chris said and what TJ said and I have no doubt they do not care that Iran is using that money to build their military.
Seems a bit crazy to me, but they don't seem to mind.
It was nice of Obama and John F'in Kerry to buy the 4 hostages with the money in spite of the US claim to never pay ransom,
and certainly those two had to know what the money would be used for everyone else did.
Think of it this way after WW1 a ( no specific country) country owed the Germans money.
The Nazi's needed that money to prepare and carry out a war.
So this country who will later be threatened with war with Germany sends Germany and the Nazi's and Hitler Millions to build weapons against them.
Makes sense to some people I guess.
