"Now that Obama has announced that he will keep around 10,000 troops until the end of 2016 and continue their occupation, Afghanistan Islamic Emirate condemns it and considers it a violation of sovereignty, religion and human rights," said a statement, using the insurgents' name for the country.
"We have always clearly expressed our stance that even if one American soldier is in Afghanistan, it is not acceptable to our nation and Jihad will continue against them."
Nato combat troops are due to withdraw from the country by December, but a residual US force is expected to remain behind for training exercises and counter-terror missions, if both countries sign a long-delayed Bilateral Security Agreement.
Afghanistan's outgoing president Hamid Karzai has refused to sign the agreement, but both of the candidates vying to be his successor in next month's run-off vote -- Ashraf Ghani and Abdullah Abdullah -- have said they will sign the deal.
Obama announced Tuesday that the 32,000-strong US deployment in Afghanistan would be scaled back to around 9,800 by the start of 2015.
Those forces would be halved by the end of 2015 before eventually being reduced to a normal embassy presence with a security assistance component by the end of 2016.
The Taliban insisted US troops should pull out right away.
"The American leaders should do now what they plan to do two years later... if the Americans really want to free themselves from the Afghan war, they should completely withdraw their soldiers from Afghanistan," the statement said.

Look!who is talking about human rights.
Promises, promises and no real end in sight. I always thought that President Bush was a low functioning disaster, but President Obama is showing all the signs of psychopathic insanity. On the other hand, who is pressing his buttons?
