It's been clear we're heading for war with Russia for years and since they invaded Ukraine its only been a matter of time.
European leaders have been really slow to grasp this to be honest, it shouldn't have taken the massing of troops along EU borders, the monster in the White House & the intelligence services speaking publicly of the threats to make them take it seriously.
Frankly, it was really only a question of whether we'd end up in conflict with China or Russia first. Politicians have been too keen to line their pockets rather than face up to the threats.
How can Mr & Ms Average prepare for a war?
By not panicking and being sensible. The war may not be fought on these shores but we will be hit with cyber attacks, interruptions to energy supplies and rising costs of imported goods.
So buy mindfully. Consider growing your own food, look to improve the energy efficiency of your home and if you're fortunate enough to afford it, supplement your utilities with solar energy and heat pumps.
Ensure you have a well stocked larder - don't need to panic buy but having a week of food you can rely on in the case of major disruption is sensible. A couple of camping lanterns, wind up radio etc.
Basically, ask yourself if your home is set up for a week longer power cut.
If you're in a position to buy quality goods then do. I'd be very surprised (shocked) if we end up in a similar situation to WW2 but with supply disruptions likely its good to steer away from fast fashion where possible.
Reduce your reliance on cloud services. You can still use them just make sure you've got hard copies of important information relating to health, finances, status etc. A few books, maybe don't throw away all your cds.
Get involved with your community. There will be more community organisations near you than you realise and they come into their own in times of stress, they will also have good contacts with local and national government and organisations.
Keep an eye on elderly and vulnerable family members, friends and neighbours. Does your old dad have enough to last in a lengthy power cut? Keep some spare torches or batteries in case your neighbour needs them in a pinch.
And finally, read the news. Not just from one paper. Take an interest in who owns and runs different news outlet/broadcasters and what their personal interests are. Their bias will determine how well you are informed, so read widely.
Are they funded directly or indirectly by Russia and its allies? Do they have a vested interested in prioritising emotive news stories not related to Russia?
And, please, don't panic buy or stock pile vast quantities.
