As I write this in the early morning hours of August 9, Russian tanks grind into a brave and isolated democratic state.

Assuming that the world's attention would focus on Beijing, Moscow stage-managed an elaborate act of aggression against Georgia.

But the world has changed since Soviet tanks rolled unchallenged into Afghanistan at Christmastime 29 years ago. Global communications now spotlight aggression instantly.

Yesterday, millions around the world didn't watch the Olympic opening ceremonies (the Chinese must be furious at the Russians). Instead, they saw images of Soviet - sorry, I meant Russian - aircraft pounding Georgian territory as Russian armor rolled over the Caucasus Mountains.

So let's discuss the background, what just happened, and what happens next.

Aleksandr Solzhenitsyn, who died Sunday (8/03) of heart failure at age 89, was a titan in Russian literature and politics of the 20th century. He survived the Stalinist purges, World War II, eight years in the gulag, a successful battle with cancer, and communist denunciation. After spending 18 years exiled in America, he made a triumphant return to his homeland in 1994.

Mr. Solzhenitsyn's life was full of contradictions. Together with another giant, Russian Nobel Prize winning physicist Andrei Sakharov and fellow dissidents, he contributed greatly to the exposure of totalitarian socialism's moral bankruptcy.

However, he was a harsh critic of liberal democracy, and of America, despite the fact that it gave him shelter and protection during his difficult years of exile. A Harvard commencement speech in which he accused Americans of hedonism and cowardice became a scandal. While his family became U.S. citizens, he refused to do so.

Russia today probably approaches Mr. Solzhenitsyn's ideal.

In March 2009, Russia will deploy modern S-300 long-range anti-aircraft missiles in Iran. By June 2009, they will become fully operational, as Iranian teams finish training with Russian instructors, according to U.S. and Russian sources.

Mikhail Margelov, chairman of the Foreign Affairs Committee of the Russian Senate, visited Washington last week. He said Iran is likely to produce a nuclear bomb "soon." Given the blood-curdling rhetoric of its President Mahmoud Ahmadinejad, it is feared that Iran may use it against Israel.

The deployment of the anti-aircraft shield next spring effectively limits the window in which Israel or the United States can conduct an effective aerial campaign aimed at destroying, delaying or crippling the Iranian nuclear program.

A rally in Berlin in front of a quarter-million glistening-eyed, bosom-clenching, swooning Germans is a historically awkward spot for a leader to proclaim his worldwide goals for tomorrow.  But that's where Barack Hussein Obama chose to declare:

"The walls between the countries with the most and those with the least cannot stand. The walls between natives and immigrants cannot stand. These now are the walls we must tear down. We know that these walls have fallen before. After centuries of strife, the people of Europe have formed a union of promise and prosperity."

That last sentence would suggest that Obama is not terribly keen about nation-states -  ours in particular.

That is why, presumably, he says that we must tear down the walls between the countries "with the most" -- that would be the United States -- and those with the least. That is why he calls for tearing down walls between "natives and (illegal?) immigrants."

Watching Obama glide through his foreign trip so far, nervous Republicans and other patriots have to hope that American voters will not view Obama through the eyes of a Hollywood casting director. That's because one could not cast a man who visually can portray a worldly statesman better.

We all must envy his ability to effortlessly drape his tall, imperially slender form in gilded Louis XV chairs in foreign palaces. Mixing just the right combination of worldly bonhomie and serious mien, his presentation (conveniently presented to the world with video but no audio) make, by comparison, Henry Kissinger, FDR and Winston Churchill all look like clumsy provincial oafs.

The visual is everything in his campaign, for when he does submit himself to the occasional press interview, his actual words read in print must make his handlers as nervous as his visual images make Republicans nervous.

His discussion of his Iraq policy is almost incomprehensible, and his understanding of the world stunningly simplistic.

I devoted six years to carbon accounting, building models for the Australian Greenhouse Office.  When I started that job in 1999 the evidence that carbon emissions caused global warming seemed pretty good: CO2 is a greenhouse gas, the old ice core data, no other suspects.

The evidence was not conclusive, but why wait until we were certain when it appeared we needed to act quickly? Soon government and the scientific community were working together and lots of science research jobs were created.

We scientists had political support, the ear of government, big budgets, and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet.

But since 1999 new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming.

What if Fed chairman Ben Bernanke and the other Fed board members actually believe that the Consumer Price Index means the same thing as it did in the 1970s?

The Bureau of Labor Statistics (an agency of the Labor Dept.) calculates the CPI, not the Federal Reserve. If the Fed Governors are unaware of the changes since then in how it is calculated, it would explain why they aren't in a panic over the current real consumer inflation rate.  It would explain why they really seem to be certain that we are not in a recession. 

It would also mean that unless they wake up from their time warp, the dollar and our economy are truly doomed.

Way back last month in June, Barack "middle name not permitted to be mentioned" Obama campaigned on the theme of "Change We Can Believe In." Now, several days later, in July, his theme should be "Change We Can't Keep Up With."

Abortion, gun control, capital punishment, FISA laws, the status of Jerusalem, faith-based federal programs, public financing of his campaign, welfare, NAFTA and free trade, and his commitment to the Rev. Jeremiah Wright and Trinity United Church have all fallen to reconsideration, re-phrasing, changed rhetorical modulation and other semantic miracles.

His Iraq position is currently in the process of glissading from "anti" to "pro" - so we will have to wait a while before saying he has actually changed it.

Which brings us as it always does in such circumstances to America's greatest fraud-sniffer, H.L. Mencken. He defined a demagogue as "one who will preach doctrines he knows to be untrue to men he knows to be idiots."
