Wasting money and exacerbating tensions

BBC:

Poland and the US have reached an agreement in principle to install a controversial American missile defence system on Polish soil.

In return for hosting part of the shield, the US has said it will help bolster Poland's air defences.

The US wants to install interceptor missiles in Poland and a radar base in the Czech Republic.

Russia opposes the project, saying it would destabilise global security and undermine its own nuclear deterrent.
