Here's my brief commentary:
I pledge allegiance to the flag of the United States of America...
No truly peace-loving nation would ask its people to pledge allegiance to any flag. Flags are for battlefields: potent symbols of a nation's military power and prowess.
Currently, our nation's government seems infinitely more committed to the well-being of a piece of colored cloth than it is to the welfare of its own people,
... and to the Republic for which it stands...
A republic is distinguished from a democracy in that the people are kept from effective self-rule by a layer of elected representatives. This indirect system is an invitation to manipulation--all but guaranteeing that,a plutocratic elite will continue pulling the strings behind the curtains.
In designing our system of government, the Founding Fathers drew much of their inspiration from Rome. The US seems well-poised to follow its tragic example of a republic devolving into a tyrannical Empire.
... one Nation, under God...
The US is beginning to show many of the earmarks of a theocracy, as its leaders become more and more adept at manipulating its citizens' religious passions for their political purposes.
Perhaps we can never fully know God's will, but the will of the people is fairly easy to ascertain. Easy, that is, unless the outcomes of major elections are subverted by such obstacles as an antiquated Electoral College, a malfunctioning Supreme Court, corrupt state governments, and a system of electronic voting that doesn't leave a paper trail.
... indivisible ...
A single power-mad administration has done what a savage bloodbath of a Civil War couldn't do: wedge the American people into two irreconcilable Blue and Red camps.
... with Liberty and Justice for all.

For the most part, the U.S. rate is three to eight times that of the Western European nations and Canada."

Item: "Unlike most Western governments, the U.S. government does not guarantee publicly funded health care to its citizens, leading to a notably high number of people suffering from lack of proper healthcare." "Enrollment rules result in millions of Americans going without health care coverage, including children. The most recent data available from the U.S. Census Bureau indicates that 45.8 million Americans (about 15% of the total population) had no health insurance coverage during 2004 This constituted a rise of about 850,000 from the previous year.
