Making things go boom isn't terrorism, but it's treated as such. Reading books about how things could be made to go boom isn't terrorism. Intent is behind terrorism more than any amount of relevant knowledge.
Every driver, however, has a terrorist tool at their hands. You can buy bottles of gas for a pittance. You can't stop the tools because the tools are so damn simple and cheap and basically include every compact source of energy we have and use (I'm waiting for the first electric battery / supercapacitor terrorist, but the energy density is probably still too low to do anything but blow your own head off).
Terrorism is designed to invite terror. To make you fear the people doing it.
By doing what we're doing as a planet now - making terror so terrifying and then beaming it into every home - we're basically playing right into their hands. One guy, with one simple device can make the news worldwide. Even if it's a complete botch (I'll say "shoe bomber", you tell me if you've heard of him, now tell me why you now have to take shoes off in airport security when you NEVER used to have to).
Want to defeat terrorism? Stop giving a shit about them.
The UK was dealing with terrorists willing to bomb cities and bring down planes since the 70's (and a lot further back than that because we were arseholes). We learned how to deal with them - ignore them. Don't stop catching them, but just make their efforts have so little impact that - in this case - they give up the terrorism and become politicians.
IRA bombings in the UK (and London especially) only invited comments like "Fuck, I'll be late for work now" or "Does anyone know which buses are still running?" Stop terrorism being terrifying and you're just some pillock who blew himself up.
It's the same with historical "terrorism". We're all scared of Nazi's and Naziist groups. Want to destroy them overnight? Change the international symbol for toilet to a swastika, and label it a "Nazi". "Where's the Nazi, I need a shit?" Instantly destroys the power in the word and the association it has.
But, no, places like France and Germany continue - over FIFTY YEARS LATER - to ban Nazi-related items. It's a Streisand effect. The best part of my walking-tour of Berlin I did a few years ago - they stop outside a building with a car park. They tell you that's where Hitler's bunker was. You're so fucking terrifying, your legacy is under a car park, mate.
People don't know how to deal with terrorists because they are far too self-centered. "What if *I* was blown up?" Fuck that, what if we allow people to get infamy so easily just because they tried to blow other people up? What if we make terrorism so terrifying they are instantly heroes for our enemies and we cower in fear of them? What if we spend billions on a international manhunt for one man in the public eye proving that MILLIONS of people are scared of one man who did nothing noteworthy himself but orchestrated others? What if we live in a world where terrorists get on the news and science doesn't? Fuck THAT.
Terrorists are cocks. And we're pandering to their media whims, like fucking dickheads. Want to see a proper reaction to terrorism?

You beat terrorists by removing the terror. Then they have nothing left.
