U.S. May Reduce Non-Military GPS Accuracy

ward99 writes "The U.S. government may be degrading GPS satellite signals, to cripple Iraqi forces' ability to use those systems during the war. This could potentially reduce accuracy from ~3 meters to over ~100 meters. Users depending on GPS systems may want to do sanity checks on any data returned by those systems during the war. The U.S. will do this by increasing the inaccuracies on the civilian C/A code, turning back on S/A (Selective Availability), by having the satellites deliberately and randomly return inaccurate information on where they are. S/A degrades GPS accuracy to only 100 meters 95 percent of the time and 300 meters the other 5 percent of the time. This will not effect the military P code."

    Missouri GOP Chairman Resignation Letter

    I grieve for our nation, and the untold suffering that will be wrought. As history has shown, you can possess the greatest armaments in the world, but if your cause and motives are not right, only catastrophe will result.

    Jack Walters

    OUR COUNTRY ABOVE POLITICS

    As the Bush administration moves toward certain war in the Middle East--a war which I believe nothing good will come from, a war which is unjust, unnecessary, and a war which will undoubtedly widen, perhaps even into world war, thereby placing our nation in dire peril--I have made a decision regarding my position as Boone County Republican Chairman.

    Wars are easy to get into, but very difficult to get out of. They can sap the moral and spiritual fiber of a nation, squander lives and resources, deplete scarce funds, cause undue hardship on all involved, destroy families, and engender hopelessness.

    I have questioned both the motives for military action at this time, and the ever-changing, illogical justifications presented to us in what has to be one of the greatest media propaganda blitzes ever force-fed a populace. Any time ground troops are deployed, serious questions must be asked and real answers demanded. The jingoistic rhetoric we are receiving does not constitute legitimate answers.

    The consequences of our planned attack on Iraq (and also probably Iran, given the size of our forces and their location in proximity to Iran), should cause us all to pause. The Pentagon has announced that we will hit Baghdad with a force almost equal to the bombing of Hiroshima. Obviously many thousands of civilians will perish, with untold thousands maimed. And for what? To liberate them? To bring them freedom? Or democracy? Or is it to really secure the world's second largest oil reserve and establish a base from which to subjugate other Middle Eastern nations? Is it also the plan for Israel to use the cover of war to forcibly relocate the Palestinian population (as has been publicly stated by some members of Israel's current government)?

    How on earth have we arrived at this crucial juncture in our country's history? How has a war on terrorism been converted into an attack on Iraq? What threat does Iraq pose to us? We must lay the blame squarely on our congress, who according to our Constitution, only has the power to declare war. For congress to cede it's war-making power to the executive branch is unconstitutional on the very face of it and effectively destroys our three branches of government. Circumventing our Constitution is very bad, and the undeclared wars, which have resulted in our recent history, have had disastrous results. Undeclared wars have no declared objectives, and therefore can widen at will, and our foray into the Middle East will likely set in motion a long-term wave of retaliation. Indeed, I believe that the administration would like to entice Iraq into firing the first blow so some justification could be paraded at the United Nations. If the United States government can adopt this unreal doctrine of preemptive attack on any nation, anywhere, at any time, so can other nations! This is how world wars begin. If the President goes into Iraq alone without a UN resolution, he will be in violation of the war powers given him last October by congress which was contingent on UN approval. A constitutional crisis will occur.--

    We, the voters, get to decide how it's going to be used ultimately, by electing and kicking out the executive and legislative branches of government.

    Yep, and I, a voter, have decided that it should not be used to kill American soldiers.

    Incidentally, the many billions of dollars of equipment the military is about to blow up in Iraq don't come from nowhere either--they are coming from the check you and I are sending to Uncle Sam on April 15. The war may amount to somewhere between 10% and 20% of our taxes.

    If that means 10-20% less for liberal social programs, I'm all for it. It's not like that check is going to be less if there is no war.

    Bugging devices found at EU

    Electronic bugging devices have been found at offices used by French and German delegations at a European Union building in Brussels, officials have confirmed.

    Devices were also discovered at offices used by other delegations, said EU spokesman Dominique-Georges Marro.

    Extra security measures have been adopted in the building, ahead of a meeting of EU leaders to be held there on Thursday and Friday.

    The discovery of the telephone tapping systems was first reported on Wednesday by France's Le Figaro newspaper, which blamed the US.

    But Mr Marro said it was "impossible at this stage" to determine who had planted the devices.

    The telephone tapping comes at a time of heightened tensions within the EU - which is deeply divided over Iraq - and of worsening relations between the US and EU members France and Germany.

    The EU spokesman said the wiretapping had been discovered during a routine inspection.

    The other delegations affected by it have not been named, but Mr Marro told Associated Press that only a small number of lines had been affected.

    Investigators from the affected countries were looking into the phone tapping, along with the EU's own security services, officials said.

    The Justus Lipsius building, where the bugging devices were found, is a regular meeting place for EU ministers.

    It houses the secretariat of the EU Council of Ministers.

    The bloc's foreign ministers have been meeting there this week.

    The building also houses the offices of the EU's foreign policy chief, Javier Solana.
