NATO Heads of State and Government meeting will be held on Wednesday 11 and Thursday 12 July 2018 in Brussels, Belgium. US President Donald Trump accuses NATO allies for their defence-spending quotas. European members have raised their expenditures as promised, Trump remains dissatisfied. At a recent speech in the state of Indiana Trump made clear his anger about Germany, in particular. He directly attacked Chancellor Angela Merkel, claiming that the United States pays for Germany's security but receives little in return. he has already indirectly threatened to pull US troops from Germany if the country does not increase its defence spending. There is an ongoing dispute whether this discussion is the tip of the iceberg, where President Trump has something more radical in his mind: United States could demand that European members directly pay for US troops to be stationed on the continent: cash for security. This would mean a radical break with the philosophy of NATO where an alliance is built on shared political beliefs. Poland's Defence Ministry’s suggestion that it would be willing to pay $2 billion a year to station additional US troops on its soil is considered result of such approach.
