On "nationalizing the banks"-- I think you meant to say that the Obama Administration has been busy trying to figure out how to undo the partial nationalization of the banks that occurred when TARP was passed because of the urgent pleas of President Bush's Treasury Secretary Hank Paulson and President Bush's appointee as Chairman of the Fed Ben Bernanke that we faced financial armageddon if we didn't bail out the banks.

Granted, I think that they did the right thing in every one of those situations, and I have consistently given Bernanke and Paulson a lot of credit for their leadership in a crisis situation, even though they were Republican appointees and I am supposedly so blindly partisan according to you.  I even give Bush credit for seeing that drastic action was necessary and for allowing it to take place. 

Then there's the federal takeover of AIG and Fannie Mae and Freddie Mac, also done under Bush by Bush appointees-- not Obama.  Again, Obama's Administration is currently working towards undoing the nationalization of the institutions, just the opposite of what you'd like to claim.

Finally, Obama's administration is currently working with Congress on financial system reform legislation that will attempt to ensure that bank bailouts never happen again, to try to make sure that we never have to make a choice between nationalizing too-big-to-fail banks and a full-blown economic depression.

As far as nationalizing the auto companies--Obama bailed them out in a manner that could fairly be called nationalization but both companies are now stabilized and starting to pay back taxpayer money loaned to them, and are putting together plans for IPOs so that the government can sell it stakes in the companies.  So Obama's Administration is busy de-nationalizing the auto companies, again just the opposite of your claim.

The medical system has not been nationalized.  Many in the Democratic Party would have preferred a nationalization of health insurance (single payer) or at least nationalization-lite (a public option) and Obama's plan that was passed did not include either, opting for health insurance reform, not nationalization at all.

Obama can't "start" dismantling our nuclear arsenal because we've been dismantling nukes for over 20 years, starting with agreements reached under Ronald Reagan and perhaps even earlier than that.  Obama is merely continuing a wise policy that has been in place for a generation.

Finally: when I point out context, you say "spin" precisely because if you allowed yourself to acknowedge the context, you'd have to admit the obvious-- no national police force is in the works-- meaning you would have to raise the white flag in one of our little debates-- again :-)
