Is it true that U.S government bonds R the safest investment in the world?

because Uncle Sam so happens to be the richest, most powerful institution in the world?

well it is safe, but the dollar is falling so there is a possibility that you might lose money sooner or later (unlikely), however the safest investments gives you the lowest returns; I would not put all my money into US Treasury, in fact international funds are doing really well right now; power does not have much to do with it, it is rather a matter of reserves and economical stability which is empowered by the free capital markets
the safest move is to diversify - put some here and some in a developing country
ta-ta!

Are you kidding me? Have you not witnessed the decline in our economy? The value of the dollar has decreased so much lately. I wouldn't invest in a US Government Bond if my life depended on it. At one time they were a safe investment, but not anymore.

no because the government can take the money away but you will still get it.
The safest would have to be japans or Luxembourg's because they are more protected.

Two years ago i would have said yes. However, the current state of the economy, mainly housing, is scary looking. I would invest in gold if i were you. It will ALWAYS increase. It will always be good somewhere.

1) Yes.
2) No.

gold is the safest investment at the moment. If you want to invest in currency the Chinese yuan or even the Euro, which is at a record high against the dollar. 5 years ago 1 dollar=1 euro, now $1=70cents (euro), work out the depreciation yourself
