And what makes you think Putin is empty handed?
China will treble its gas imports directly from Russia and looking at the current situation India will also look to import Russian gas. Both these countries are 40% of the world's population will jolly well make up for Europe. Not to mention southeast Asian countries which may also need all the oil and gas.
Comparing Russia to Iran in geopolitical context is immature and irrational.
The point is, there will always be buyers for oil and gas as long as it exists on earth.
Can Europe sustain its shaky road to recovery when Russia shuts off the pipes in retaliation to sanctions? No it won't.
In fact with the current situation, Germany, UK, Sweden, Poland and France are the only 5 survivors in the significant league. You can count Turkey out of the EU officially.
Qatar pipeline is not something which will materialize with a switch button. It will take time, money, effort and bandwidth. Till then they cannot impose sanctions.
Simple as that. It is waiting game on both the sides.
Sanctioning Russia would be the stupidest move NATO countries can do. They have much more to gain collaborating with Moscow than going against their interests.
You probably don't read the news I'm sure. China's factory output has dropped off, the price of iron ore has dropped on the international market because demand from China has weakened. All this means, lower growth which means, China won't be replacing Europe anytime soon for all that Russian gas consumption.
And new gas fields are being discovered in China and other countries all the time. Not to forget 'shale gas' which is the new technological break through in energy industry in decades. This is also why the United States relies less on Gulf oil today than it did a decade ago. Again, buyer has power, not the seller.
India faces similar situation. Its economic growth has declined considerably. Its current needs are being met. Any increases in gas consumption, will not translate in to some voracious appetite for Russian gas anytime soon.
Whether you count Turkey out or not, fact is UK, France and Germany remain the anchors of Europe and in pretty healthy shape. Calling them 'survivors' is quite the understatement.
Qatar doesn't have to lay down pipelines. Even if pipelines are to be laid down; in the meantime, liquified gas can be shipped to Europe, its NOT a problem at all.
Sanctioning Russia is the way forward, the only other option is military standoff. So yes, sanctions are the winner here since no one wants needless bloodshed. G8 has effectively been dissolved cuz Russia has been thrown out of major economic decision making of the world powers.
Russia stands to lose, not Europe. Your insistence on Russia holding the chips is failure to comprehend the basics of a market economy which is, the 'buyer' has the power, not the seller.
