Now we have to rely on the US and there is nothing worse than relying on the US. Europe just showed once again it failed to learn anything from the Suez crisis. The US should never be trusted. They are not a reliable and only care about themselves.
Europe has been mismanaging its relationship with the BRIC since the end of the Cold War. We are too dependent on NATO. Not that there is much to expect from the EU. Every addition since 1995 has only weakened it.
Also Norway can replace a lot of the Russian gas supplies.
