At the new conditions in the Europe, especially NATO expansion to the east, new NATO air-defense systems around Russia and unstable conditions in Georgia and Ukraine, Is there any ability in European countries to defend themselves without the US help if a war occurs between them and Russia? In my opinion, most of Russia weapons, conventional and unconventional, are more developed and better than Europe countries. Even some of their weapons are better than US, for example missiles and air-defense systems.
And if it is true, can’t we consider this as a weak point for European and doesn’t it make the European countries’ safety depended to the US help while the US's safety isn’t depended to the European?
There can be also a comparison between NATO with US and Shanghai Accord.

NATO countries would have every chance in the world to defend themselves against a Russian invasion primarily due to the logistics of invading the west are not in Russia's favour.

As the old Soviet Union it was a possibility as its jumping off point would have been the German/Polish border but now Russia would need to battle its way through most of Eastern Europe and that in itself would be a battle given the popularity of Russia in those states, lets face it glaring problems were exposed during the Russian invasion of Georgia.

Personally I doubt Russia could take Poland let alone the rest of Europe.

However I would also suggest that you have failed to grasp one small aspect, the security of the USA does depend on the security of Europe and vice versa so the chances of Europe being left to its fate are incredibly slim in my opinion.

Russia has a large military but Russia is large. Largest area for any nation on earth, nearly twice the size of the USA. But, Russia has less than half the population of the USA to cover all that land.
The USA shares a land border with 2 countries, and both Canada, and Mexico do not seek the USA harm.
Russia shares a land border with 14 countries, many do not like Russia, even a little bit.

The closest neighbors the USA has that may want the USA taken out is Cuba, off the coast of Florida, and Russia, off the coast of Alaska.
The USA will not worry about Cuba attacking.

If Russia pulled the trigger on the west Russia would have to contend with its other neighbors attacking Russia. It would be a mess, even without using nukes.

At the end of the Cold War, the Soviet Union had a total population of nearly 290 million, and a Gross National Product estimated at about $2.5 trillion. At that time, the United States had a total population of nearly 250 million, with a Gross Domestic Product of about $5.2 trillion. That is, the population of the United States was smaller than that of the Soviet Union, with an economy that was only twice that of the Soviet Union. Two decades later, Russia's population is about 140 million, with a GDP of about $1.3 trillion, while the population of the United States is over 300 million, with a GDP of $13 trillion. Today, the population of the United States is twice that of Russia, and the US economy is ten times as large.

That is to say, with considerably more advantageous population and economic resources, the Soviet Union was destroyed by the effort to remain a peer competitor with the United States during the Cold War. Presently, with relatively more modest resources, it is beyond the capacity of the Russian Federation to mount any sustained challenge to the United States or NATO beyond the immediate area of the former Soviet Union.

When I do a comparison between Russian and European weapons, I feel that the Russian weapons are better than European weapons.
For example the Russian Air force is second in the world and utilizes the most advanced airplanes. For example I can’t find any European airplane deals with Su-T50, although it hasn’t been mass produced. And the other airplanes such as Su-37, 34,33and MiG 29, 31 and 35 are better than European airplanes such as Rafale, EF or Mirage 2000 or at least are in the same position.
They have most developed combat helicopters (Mi28 and kamov 50, 52) and they are better than European helicopters and are almost as dangerous as the US combat helicopters.
The Russian Air-defense systems and missiles are great and are best in the world. Just remember S-400 or S-500 and Alexander.
They have a large and strong armored force. T90, 94 are good examples. Although the European Tanks such as leopard and Leclerc are very advanced.
Their Navy is not as developed as European Navy except that their Submarines which I think are better than even the US submarines. For Example Victor class submarines are masterpiece.
Also their Electronic technology and drone are their weak points. Although the European countries don’t have advanced drone. In this part the US is first and Israel is second.
Russia is one country with one army while the European countries consist of several countries with several army. So the management of a war will be easier for Russia.
And the last thing, Russia has the largest nukes stockpile even more than US. I think if they blow up their nukes in their land, the whole of the world will be destroyed.
It is my opinion, maybe it is wrong.

I just want to have a comparison between their armies. For example "which army is stronger, Pakistan or the UK?" and "could the UK occupy Pakistan lonely as regard the long distance between them?" are two question with two different answers.

Do you think the Europe has an independence policy in the world? I don’t think. They are completely depended on the US while the US isn’t. They can’t remove any crisis even in the Europe. The Balkans crisis is a good example. Without US help could they solve it?
Could they dare to attack Afghanistan and Iraq and manage their war without the US help if a terrorist attack would occur in Europe? I don’t think. But the US could do it lonely.
In fact they are subsidiary player and the US is main player. The US needs them when they want to use” The international community” phrase and then they say quickly “yes we are the international community”. The international community is care about the Syria, The international community is care about the Iran’s nuclear activities, the international community is care about the elections in Russia, the international community is care about the freedom in china and so on… They support Israel not because they are care about Israel’s security but because they scare from the US, the Israel’s godfather.
In fact the excessive reliance to the US makes them lazy and I think they are losing their influence in the world gradually especially when the new powers in the world like china and India are emerging.

I said a war between Russia and NATO without the US help but you are comparing between the US and Russia.

The population is not all. If it was the India and china would be the powerful power in the world. Even more than US.

I would argue that you are living in a long past era.
You seem to be pressing the idea that because Europe doesn't maintain huge armies they are ripe for invasion but you are over looking the point that with the demise of the Soviet Union the threat to Western Europe from a conventional invasion all but disappeared.
