David Lindorff lays out the grounds for impeaching President Obama:

Let’s start with the war in Afghanistan, which Obama has taken full ownership of with an escalation that will bring the number of US troops in that country (not counting mercenaries hired by the Pentagon and CIA) to 100,000 by this August.

The president has authorized the use of Predator drone aircraft for a program of bombing conducted against Pakistan which has illegally expanded the Afghan War into another country without any authorization from Congress. These pilotless drones are known to kill far more innocent bystanders than enemy targets, making them fundamentally illegal on principle as weapons. Furthermore, this wave of attacks in Pakistan is a war of aggression against another nation if the word “war” is to have any meaning at all, and as such it is illegal under the UN Charter. Indeed initiating a war of aggression against a country which does not pose an immediate threat to the invader is described in the Charter and in the Nuremberg Tribunal Charter as the gravest of all war crimes.

The president, as commander in chief, has also, in collusion with Attorney Eric Holder, blocked any prosecution of those who authorized and perpetrated torture against captives in the War in Iraq, the War in Afghanistan, and the so-called War on Terror–notably Federal Appeals Court Judge Jay Baybee, and Berkeley Law Professor John Yoo, who as Justice Department attorneys authored the legal briefs justifying torture– and has in fact continued to permit the application of torture against captives. All of this is in clear violation of the Geneva Conventions, which as a signed set of treaties, are part of the law of the United States. Under those treaties, failure on the part of those up the chain of command to halt or to punish those who commit torture are themselves guilty of the crime of torture.

As commander in chief, President Obama has also overseen a strategy in Afghanistan of expanded attacks on civilians in Afghanistan. As in Iraq under the Bush administration, this current phase of the war in Afghanistan is seeing more civilians killed than enemy combatants, because of the widespread use of weapons like helicopter gunships, aerial bombardment, fragmentation bombs, etc., as well as a tactic of night raids on housing compounds where insurgents are suspected of hiding–raids that frequently lead to the deaths of many women and children and innocent men. It is significant that even the recent execution-style slaying of nine students, aged 11-18, by US-led forces, has not led to an investigation or prosecution of a individual. Rather, the incident is being covered up and ignored, with the clear acquiescence of the White House and the leadership at the Pentagon.

It is also widely believed that under the command of Gen. Stanley McChrystal, who is known to have directed a large-scale death-squad operation in Iraq before moving to his current position, a similar death-squad campaign of assassination is being conducted now in Afghanistan--a campaign that like the notorious Phoenix Program in the 1960s in Vietnam, is almost certainly resulting in the deaths of many innocent Afghans.

Domestically, the president has continued to allow the policy of detention without trial of hundreds of captives in Guantanamo Bay and other prisons, including Bagram Airbase in Afghanistan, and his director of national security has even stated that it is the policy of this administration that American citizens deemed by the administration to be enemy combatants or terrorists may be targeted for summary execution. Such officially sanctioned state murder is a blatant violation of the Constitution’s insistence that every American has a right to a presumption of innocence and to a trial by a jury of his or her peers.

The president has also continued and in some ways even expanded the Bush/Cheney administration’s program of warrantless spying by the National Security Agency on the electronic communications of millions of Americans. A part of that program, the monitoring of communications of a now defunct Islamic charity, was just declared illegal by a federal judge in a case that was brought against the Bush/Cheney administration, but which continued to be defended by the current administration. There has not been a decision as yet by the Obama administration about whether to appeal that decision. While the case in question does not represent a crime by the Obama administration, it is clear that it only represents the very tip of the huge iceberg of domestic spying, and the administration’s vigorous efforts to shut down this case or to win it are clear evidence that the NSA is continuing to do the same thing on a vast scale. In fact, the only reason this case even got to trial is because of a government error that resulted in a memo describing the monitoring being mailed inadvertently to the victims of the spying.

While we’re at it, I would also suggest that there is ample evidence to call for the impeachment of Treasury Secretary Timothy Geithner, who appears, as head of the New York Federal Reserve, to have colluded in an effort to cover up a massive fraud at Lehman Brothers, and who has subsequently as Treasurer, participated in unprecedented giveaways of taxpayer funds to several of the country’s largest banking institutions.

The above enumeration of criminal and Constitutional transgressions makes it clear that this president, like his predecessor, has, almost since his first day in office, continued down a road of criminal and unconstitutional behavior that threatens the survival of Constitutional government in the United States.

Let me state it simply: President Barack Obama, as well as Attorney General Eric Holder, Secretary of Defense Robert Gates, and Treasury Secretary Geithner, should be impeached for war crimes and high crimes against the Constitution.”
