The Fed Can Stop Inflation

i think, i think they are in the process of working, but it just takes a while. Paul voco proved that in the early 19 eighties. He had to raise interest rates as high as 20%. So i've no doubt that the fed can stop inflation. I think the question is, how much pain are they gang to inflict? How high do rates have to go? And how long do we live through this sort of stagflationery period?
