Just when you think one can't get any more ridiculous, there comes you. Clarify how Afghan refugees are the biggest obstacle in your prosperity and prove that it's only because of Afghan refugees? It's not the refugees taking aid from every country in the world and dispense the money in their pockets, it's your politicians. And we, along with the ongoing wars, face the exact same problem in politics.
Of the 10.4 million refugees under UNHCR's mandate between 2005 and 2009, the largest numbers were being hosted by Pakistan (1,740,711), Iran (1,070,488), Syria (1,054,466), Germany (593,799), Jordan (450,756), the UNHCR's '2009 Global Trends' report reveals.
Pakistan hosted the highest number of refugees --mainly from Afghanistan -- also compared to its national economy.
As such, it hosted 745 refugees per 1 USD GDP (PPP) per capita. In 2009, one out of four refugees in the world was from Afghanistan.
