To challenge something you have to represent it correctly
I haven’t much time today. I note that the British Chancellor has made an emergency speech to the House of Commons last night (August 11, 2011) – Statement on the global economy. He claimed that the fiscal austerity had made the UK a “safe haven” for investors. The reason that demand for gilts is high at present is because the bond markets know the UK has no default risk. I also noted Paul Krugman’s wrote a blog in the New York Times yesterday (August 11, 2011) – Franc Thoughts on Long-Run Fiscal Issues – where he challenges Modern Monetary Theory (MMT) directly. To challenge something you have to represent it correctly.
