Out of curiosity, which countries are you referring to? Do you have a strong case that countries plagued by worse terrorism are better off by not going to war?
Faulty categorization. Why focus only on countries suffering from terrorism? How about when one country routinely screws another causing loss of life?
But focusing on terrorism, Cuba was plagued by terrorists (although perhaps not as bad as 9/11), some of whom found harbor in the US. The US is refusing to turn over suspects, and is also refusing to prosecute - which is an even worse stance than the Taliban took over Bin Laden.
So you're suggesting Cuba going to war would have been better for its people?
I think India, for instance, should have crushed Pakistan years ago. They had plenty of opportunities.
(Sarcasm) Yes, just like their previous 2-3 wars solved that problem. (End sarcasm)
They didn't, and so Pakistan is launching terrorist attacks against India to this day.
To minimal effect on 99.9% of the population. They're more likely to be hurt by antiterrorism policies than actual terrorism.
Even putting aside nuclear weapons, one or two assaults by the Pakistani army can kill far more than the terrorists dream about.
And speaking of India, suicides by farmers due to questionable policies kill more than the terrorists from Pakistan do. Internal strife (various riots, massacres, conflicts) kill more than the terrorists from Pakistan do.
But that's OK: India's more concerned with deflecting attention from those problems to someone else than actually, you know, solving problems.
