Would you fight for your country..

America has been involved in 94 wars since it became a nation but only one of them involved foreign forces actually 'invading' (though technically those 'invaders' were former landlords stepping in to stop America invading its neighbour in the North) because basically from an invasion perspective America is an island<span style="line-height: 18.2px;">, (albeit an effing big one), </span><span style="line-height: 1.4;">with 5000 miles of water on either side that makes it quite hard to attack as long as they keep their nextdoor neighbours sweet. America learnt one thing from that 1814/15 invasion: to defend a big island you need big ships, </span><span style="line-height: 1.4;">which is why the US Navy has big ships </span><span style="line-height: 18.2px;">(well, they also learnt that rockets have a red glare but the significance of that didn't occur to them until 150 years later). The much later attack on </span><span style="line-height: 1.4;">Pearl Harbour (which wasn't a 'boots on the ground' invasion) gave two more big ship lessons - if foreigners also have big ships America needs even bigger ships and it would be really good if foreigners don't have big ships at all. All of which means that a military invasion of the American mainland by foreigners is highly unlikely. The biggest threat America faces is itself and at present y'all seem quite content to do nothing about that because of a piece of paper written over 200 years ago. </span>
