I have no problem with pushing for something to happen that I think should happen even if I think it won't happen.  And I see no real purpose to NATO anymore.  

The US gets nothing out of NATO that it couldn't get with decent diplomacy. The US made clear after 9/11 that it doesn't need or want any NATO countries coming to its defense if it is attacked.  The effort in Afghanistan exists by negotiation anyway.  If the first George Bush had been president instead of his idiot son, the entire world would be in Afghanistan helping there with or without NATO existing.  So the only thing the US gets is the ability to pretend (at this point) to have some control over Europe.  Isn't Europe tired of that at this point?  Isn't Europe unlikely to engage in massive early-20th century style wars again?  And can't Europe do it's own combined defense against external threats (including Russia) without needing us there?  I think so.

You may think disbanding NATO won't happen, but that doesn't mean we shouldn't be pushing for it.  

Now ... maybe you like NATO.  I don't know. I couldn't tell from your response.
