In a Comment is Free piece in The Guardian, Matthias Klein argues that it is counterproductive for the UK to publicly declare Hezbollah to be a terrorist organization.
In the amazing logic of the Left, his argument is roughly this: Since in the pro-terror world of Hezbollah and their friends it is considered a badge of honor to be vilified by the West, and conversely it is considered awful to be friendy with the West, then any Western vilification of Arab terror groups makes them stronger.
As usual, the argument is high on cleverness and low on common sense. While indeed Nasrallah said that this classification was a "badge of honor," we have seen pro-terror groups use the prestige that comes with being treated with respect by the West in an exactly similar manner.
In other words, Klein naively assumes that Nasrallah is telling the truth when he says that he is happy.
It never seems to occur to him that, perhaps, the reason to label Hezbollah as terrorist is because they are, in fact, terrorists. Klein's argument against that is that since the West is not consistent in this labeling (for example, not labeling Israel as "terrorist") then it should not label anyone - a manifestly absurd position.
The idea that coddling terrorists will take away their bite should have been discredited long ago, but to the clueless Left, this is still considered an intelligent argument.
