IMF chief worried about US shutdown, and even more on raising the US debt ceiling

I watched last night that IMF chief Chiristine Lagarde is very much worried about the US Govt showdown (now on its fifth day) It may have long term damage not only to US economy but to the entire world as well.  US problems/woes could drag the rest of world economy with it.

It is a "mission critical" in a speech she delivered at George Washington University | October 3, 2013 (from Nation)

If US fails to resolve the budget and raising the debt ceiling, US may default on payment of its debt papers and result in massive default (like your credit card company cancelling your credit card) and US may have to pay in cash.  Will this make life for Americans less gloomy (many dont frequent restaurants and coffee shops as they used to pre October 1, 2013

Japan must also reform its economy;  its debt has reached 250% of its GDP with its per capita debt standing at $90,000 for every Japanese.

Do you agree with Christine?  Earlier, I made a post on the bad shape of Japanese economy.  Is Japan now suffering for its WW II sins?

Many of the Asian markets were lower yesterday due to US shutdown.

Are Asian markets and US related?  Can you see the relevance of US problems and Asian capital markets?
