Scanning the various news websites around western Europe and the US, you would never know that there hasn't been greater danger of the outbreak of a third world war since the 1950s and 1960s.
Two historic powers have risen again and seek to reassert themselves as pre-eminent in their regions: China and Russia. Unnatural allies, the USA's failed policy to remain the global hegemon pitches it - and Europe - into direct conflict at two primary flashpoints: Eastern Europe and the South China Sea.
Russia maintains the largest tank army in the world. It could roll across the Suwalki Gap before anyone even knew what was happening, cutting off the Baltic states. NATO's expansion to Russia's borders is an unacceptable threat to Russian national security; the Russian Empire has always sought to dominate the Baltics, Belarus and Ukraine to provide a buffer between western Europe and the Russian heartland; due to the flat, indefensible terrain, these countries have always posed as mere highways for the invading armies of Poland-Lithuania, imperial Sweden, Napoleonic France, Wilhelmine Germany, Austria-Hungary and Nazi Germany. Russia also seeks possession of warm water Baltic ports and to secure the interests of its nationals in those states. It matters not that you don't consider these points valid: The Russian mindset is all that matters.
The Baltics and Ukraine are militarily indefensible and NATO cannot even attempt to do so without risking a nuclear war -- because Russia has more nuclear weapons than the US, and it has the means to deliver them hypersonically. And Russia has currently amassed weapons and troops at the Ukrainian border. It looks very much like they're poised to cross and invade it any time now.
Which brings us to China. China's navy is now larger than the US navy. It has longer range anti-ship missiles, hypersonic capability, and a rapidly growing thermonuclear arsenal. They are being very open and honest about their designs on Taiwan. As open as Hitler was on Poland. They have threatened Japan with nuclear extermination should it intervene in their conquest of Taiwan.
So -- the board is set. Don't be too surprised if a coordinated, simultaneous attack on Ukraine, the Baltics and Taiwan is executed by Russia and China. The US and NATO can either fight or not. If they fight, they and particularly the US cannot win the ensuing two-front war. Any attempt to do so runs the serious risk of escalating into a thermonuclear exchange which will revert those of us who survive to the status of betumored medieval peasants, starving and unwashed in a cold, dark and poisoned world. Even if the war were to stay conventional, the US still loses. Every. Single. Time.
The Baltics, Ukraine and Taiwan are not worth starting WW3 over. NATO should not have expanded to Russia's borders. A commitment must be given that NATO will expand no further. It may even be necessary to disband or shrink NATO. China cannot and will not be hemmed in. It must receive a guarantee from the US that America will not intervene during its annexation of Taiwan.
These are unpalatable prospects for a small nation such as Ireland. Our instincts are naturally supportive of smaller nations. But the reality is that while the US was wasting the past twenty years hunting for bearded nobodies in the caves of Afghanistan, Russia and China rose again as Great Powers with enhanced nuclear and conventional capabilities, with a shared common enemy. Russia and China are empires. Real, hardcore, old school empires -- the kind that would happily relocate or genocide the entire population of Ireland in the morning if it suited them. They also have unspeakable military capabilities and the nationalist zeal to use them.
The world map is set to be redrawn before the end of this decade, certainly by the end of the next one - and possibly a lot sooner. Democracies will fall. Alliances will be disbanded. And the world is set to be divided into three spheres of influence, all very different. If this isn't allowed to happen by means of diplomacy and a strategic US withdrawal from certain regions, there is going to be a world war that will make the last one seem mild by comparison.
I hope I scared the shight out of you.
