United for Peace and Justice is organizing what looks to be a great opportunity to demonstrate
this Saturday, April 29.  The march will start at noon
just north of Union Square, proceed south along Broadway to Foley
Square, and end with a Peace and Justice Festival; logistical details
are here.

Last week, Bill Camarada posted a call for us all to commit ourselves
to participating in massive anti-war demonstrations for the foreseeable
future that will—we must hope against hope—make some difference to
the increasingly insane course of events:

I never thought I’d say this, but the era of the political demonstration is back.

The immigrants’ rallies are a harbinger. But we now need to prepare for something far bigger.

It is now clear beyond a doubt that George Bush plans to attack Iran, almost certainly before Election Day, and quite likely with tactical nuclear weapons.  […]

As this manufactured crisis approaches, we
need to get out into the streets for the largest peaceful anti-war
demonstrations in American history. We will need to get far out in
front of the politicians. Given the horror of what’s in store, we have
no choice.

And we can do it. The largest anti-Vietnam war
rallies brought together roughly half a million people. We can run
rallies all over the country, and bring together 20,000,000 people to stop this insanity. […]

This fall’s marches need to be impeccable. Learn the lessons the immigrants have taught us: bring your American flags. We are Americans. We speak for true patriotism.
And we don’t want America, our country, in our generation, to be
remembered as the mass murderers who unleashed a horrifying new age of
nuclear warfare.

UPDATE: OTHER DEMONSTRATIONS.  There will be a demonstration this Saturday at Rice University in Houston
calling for the U.S. to put more resources into stopping the kidnapping
and brutalization of Ugandan children at the hands of the Lord
Resistance Army.  And demonstrations are being held this Sunday in Washington D.C. and elsewhere across the nation protesting the ongoing genocide in the Darfur region of Sudan.
