The last round of protests were big, and did make a significant difference in how the media covered the situation, but more - much more - needs to be done, and soon. On Sunday, about 10 million people are expected to take part worldwide in protests in over 400 cities in over 60 countries, on every continent... even Antarctica. That's a huge start, but more is needed.
The US going to war is hardly a trivial matter, and such protests shouldn't be just about the typical people who protest everything -- this war is just a bit more serious than that, given that over 50% of the country doesn't even want war under these circumstances.War is by far a certain thing, and there has been some serious talk in the financial world that our economy is on far shakier ground than most people suspect. Any serious unexpected consequence related to an invasion of Iraq could send our economy into a tailspin that could take years to recover from.
So, go to the protest, but don't go alone. Invite your family along. Invite your neighbor. Have a picnic. Go with others in your church or other groups you are a part of. The situation is too grave not to take a side on. In a world where the government has made it abundantly clear that they can do whatever the hell they want, there's safety in numbers and power in unity.
If they can protest in Antarctica, you can protest too. Get out there. Spread the word. Even though war seems inevitable, the tide is turning... don't just sit there, help it along a little bit!
