I have hope that war with Iran will not happen. For the simple reason that Iran is already to strong to attack. I suppose it is possible for Israel to attack Iran, even though the Israeli generals must know that it would be a doomed enterprise. Much like the Japanese generals who launched the first strike on Pearl Harbor even though they knew it would bring ruin to Japan. Optimism may make no more sense than pessimism, but I still have hope there won't be another war.
Iran now has all the power that they have been seeking for so long. They have tough friends, in Russia and China. Israel may have advanced military hardware, but it is not enough. They are vulnerable to oil supply disruption. I don't know what the state of their finances are, but with America and Britain both as close to bankruptcy as they are, how can Israel go to war? Israel has always relied on US and British financial backing (credit) and energy supplies.
In the 1980s Russia had a lot of highly advanced military hardware. When they went broke, they were not able to use it, and it didn't do them any good. Britain went into WWI when it was technically bankrupt, although few knew it. They were only able to fight because they had the US to bankroll them, and supply fuel.
Now it is Russia, China, and Iran that have lots of cash and fuel supplies. No matter who wins the initial skirmish, they will eventually prevail. The Central Asian nations, Kyrgystan and Kazakhstan, etc, also have critical energy resources and are strategically important. Russia, China, and Iran are building a huge integrated pipeline network, for both oil and gas, and it crosses all over Central Asia. It feeds China, and Europe, and soon India. These nations' futures are linked and they will support each other. Europe, including Britain, is now utterly dependent on Russian natural gas, and Russia can cut this supply line, as Putin recently demonstrated. All energy importing nations are counting on receiving a slice of the Kazakh oil pie (although there is clearly not enough to go around). So, I believe no European nation can support a US/Israeli attack on Iran. India is waiting in line, hoping to receive Iranian and Kazakh oil and gas. They won't support the US. Australia is having fiscal pressures of its own, similar to the balance of trade problems, and real estate bubble problems that the US has. They have made important energy deals to supply liquified natural gas to China. Australia will not support us. South America will not support us either, gloat is more likely.
As for Israel, I do think they are in trouble, and they won't be able to fight their way out of it. For that matter, Taiwan is also in trouble. We will not be able to defend them either when China finally comes to retrieve her “stray province”. The world is changing. People should deal, not fight.
