The basic question is not whether terrorism can be defeated; even third-rate dictatorships have shown that it can be put down with great ease. The real problem is the price that has to be paid by liberal societies valuing their democratic traditions.
Over the last two decades considerable academic debate has taken place concerning the correlation between differing political systems and terrorism. It has become somewhat conventional wisdom to argue that liberal democracies are disadvantaged, when compared to illiberal non-democracies, in countering terrorism because of institutional constraints that prevent them from responding to terrorism with repression.
It appears that liberal democracies have mainly five inherent weaknesses against terrorism: freedom of movement, freedom of association, an abundance of targets, constraints of the legal system and the media. Also democratic societies are particularly vulnerable to a form of violence that incites their governments to overreact and subsequently lose legitimacy, along with their ideology , as will the impact of freedom of the press and other media within liberal democracies.

There is concerns that countries who open their borders to immigrants and political refugees could potentially offer infrastructures to international terrorism.

Over the last two decades there has been a transition process involving the dismantling of former police and tight border controls which had existed
