If President Barack Obama is reelected to a second term, the United States economy will "hit a Greece-like wall " warned Republican presidential candidate Mitt Romney in an interview with FOX News Channel Monday.

" I think before the end of his second term, if he were reelected, there's a very high risk that we would hit a financial crisis that Greece or Italy have faced, " Romney said to host Bill O'Reilly. "I think it's also very possible that we would continue to see very high levels of unemployment . I think you would see industry in this country, entrepreneurs, big and small, decide to go elsewhere, to take their investment dollars to other nations. This President has put together the most anti-investment, anti-growth, and anti-job series of policies that I've seen since Jimmy Carter."

O'Reilly also asked if Romney considered Obama a "Socialist" for having economic policies that mirrored European Socialist models.

"I consider him a big government Liberal Democrat I think as you look at his policies you conclude that¨he thinks Europe got it right and we got it wrong. I think Europe got it wrong, I think Europe is not working in Europe and I will battle him on that day in and day out, " Romney replied." But I probably am not going to be calling him names, so much as calling him a failure."

During the 30 minute interview, Romney also took a shot at Newt Gingrich, his chief Republican opponent for the Republican nomination. Romney criticized the former Speaker of the House for his proposal to target "activist" federal judges with law enforcement.

" His comments about the justices and Congress and sending the Capitol Police to bring in judges--- That's not exactly a practical idea or Constitutional idea ", Romney said ." Let me tell you, there are a lot of decisions by judges that I vehemently disagree with but I also agree with the Constitution. The solution to judges out of control is not to tear up the Constitution and say that the Congress of the United States now becomes the ultimate power in this country."
