Wary Poland goes on military spending spree

A good example of how international peace and stability is not a given, and hence the need to invest in arms. Compare this example of Russia with ISIS as examples of disruptions to world peace...where Japan uses the ISIS threat (recent beheading of Jap hostages) to justify its military spending and build-up and amendment to its post-war Constitution to allow it to send troops overseas.

For those who have done the editing worksheets recently, you may recall the error about "the youth's future is under their own thumbs'. Compare this with para 2 of the article below: 'under Moscow's thumb'.  The expression 'under XXX's thumb' usually has a sinister ring to it and conveys the idea of the reluctance on the part of the subject under the influence of the thumb.
Think for instance 'I have him under my thumb'.....that means I have total control over him and any time I feel like it, I can simply crush him to death. Those familiar with the Chinese classic, Xi You Ji (Journey to the West)....there is n expression where Sun Wukong cannot escape from the Buddha's five-finger mountain. I believe it has the same idea.

Examine the extent to which expenditure on arms and the armed forces is justifiable in the modern world. (Cam. 2014)
