Questions that baffled me

The U.S. Treasury reports the federal budget balance on a monthly basis.The deficit for the first 11 months of the U.S. fiscal year was $589 billion in 2014. The deficit reached a peak of $1.4 trillion in 2009. However, it has been improving since then.

Now they are contemplating to leave EU again and in the short term it may have some risks. Some of them that come to my mind are below.
