Of course, technology is very important now. It's there, its available. It's there to be use however you see fit. You can use it and the jihadist can use it.

But it's not technology that makes them that way.
If the Europeans truly wish to improve their NATO contribution they can show it simply enough. They can establish professional armed forces, like those of the UK. And they can acquire more advanced technology. Indeed, unless that happens soon the gulf between the European and US capabilities will yawn so wide that it will not be possible to share the same battlefield. Alas, I do not think that sharing battlefields with our American friends - but rather disputing global primacy with them - is what European defence plans are truly about.
