Imagine, if you will, that Plaid Cymru decided to adopt an extremist militant policy. Mindful that the whole of the island of Britain had once been their land, they decided to declare war on the United Kingdom. Not having access to any heavy weaponry, they resorted to such small arms, mortars and missiles as they could smuggle in or manufacture, and a campaign of suicide bombing, in an effort to demoralise and terrorise the British into dismantling the United Kingdom and re-instating the rule of the Romano-British Welsh over the whole island.
Now imagine another scenario. After the Anglo-Saxon invasion of the 5th to 7th centuries, a remnant of the Romano-British Welsh are driven to the Welsh and Cornish fastnesses, but the majority spread across the world, particularly to Patagonia and Pennsylvania, where they flourish and make enormous contributions to the nations in which they settle, most of all by bringing the incalculable blessing of Welsh (or ‘Bourbon’) whiskey to the USA. However, in the late 19th century, an international Plaid Cymru movement springs up with the aim of returning the worldwide Welsh to a re-established State of Britannia Superior. Since they have by now become Americans, they have the will-power and the weaponry – and they overthrow the rudderless and divided United Kingdom.
The first paragraph is how Israel sees Hamas. The second is how Arabs see Israel.
