terrorism is the muslim worlds answer to globalisation.
the world is so polarised now, and with Australia, England, the US leading wars of invasion into muslim countries, we are more at risk.
any country now has an obligation to have stricter border control and screening procedures. the way these procedures have developed is by people at the top saying "do something" and people at the airports visa offices etc making up a whole lot of procedures and implementing, so they can say its been done. knee jerk reactions which people then have to put into place/ urdergo.
some of these procedures have picked up and prevented terrorist incidents from happening, already.
some of them are outrageous, like your son having to fly back to another country for an interview. a new form of mccarthyism is moving around the planet, and countries also are spying on and punishing their own citizens, under laws in which requirements for evidence have been removed.
i can see the problem. but who can think of an answer, in this globalised world. if our own political leaders have no power, and jump to the commands of a larger power, what hope has the common citizen got of solving anything?
