This artical reminds me of a very old saying in Chinese,I just gonna put it in English as "there are no permanent friends and foes ,only eternal interests."
From a macro point of view,the crisis in European countries affects not only Europe,but also the rest of the world,especially the US.Yet,according to the artical above,we come to know that the US is not going to "help".Rigth or wrong?There is a answer in erery one's mind.The US puts its own benifits and interests first,and it is every country's priorty to protect itself.
So,we all need friends and partners,but,DO think for yourself first and do not totally depend on someone else.You/me/ourselves,are the ones who you/I/we can depend on at last.
