The ultimate fear is that the US in supporting its pet and ally Israel will again get itself into another unwinnable and extremely expensive war on the periphery. The financial instruments I will focus on are the 10-year & 30-year treasury bonds, and the long-term US Treasury bond exchange traded fund (ETF) TLT. A long mortgage bond has a negative duration, a short US Treasury bond has a positive duration. Whoever is responsible, it is yet another attack on the American periphery, with no end in sight. If long-term US Treasury bonds offer no safety for investors, then their money will seek out alternatives.
