An escrow account would be for financial (money) aid only. Once a nation offers financial aid to another nation, that amount of funds would be placed in an escrow account. The purpose would be to keep the donor nation from accidentally spending below the amount of money offered in aid, thereby screwing up the aid offer. While the funds would be in a seperated (escrow) account, the money would still be subject to raiding during war.
EDIT: 
In the old Forum poll the OP was submitted under joeliscob (I'm not trying to take credit, merely keeping it alive), the votes were YES-287; NO-39.
If you take the time to look, please take time to vote, thank you!
FYI- of course, now that I have edited my post, all the votes have dissapeared. At the time of this edit, there were 4 YES votes.
