Retirement tax questions

as I read that last paragraph, the contributions she made prior to 1999 are not taxable by the US since she was not a US person at that time.  presumably she paid taxes on those contributions way back when,

 

The 50% pension credit wouldn't apply because she didn't pay it to Japan.  If she had that could be a different story.  

 

why don't you think that last paragraph applies?

 

let's see what others say.
