Europe is on the brink of collapse.
The prime minister of the Netherlands just resigned over the issue of austerity. President Sarkozy of France will probably lose his election to the socialist candidate Francois Hollande over the issue of austerity. The grand deal to save the euro and the European economy is about to collapse. The economies of Spain and Italy are falling under their own weight and cannot achieve the austerity targets agreed upon by the rest of Europe.
Europe's economic collapse will have a negative impact on the U.S. economy. There is no one left to bail out Europe, if they don't solve their own internal problems.
