歐盟領導人周末前聚集在布魯塞爾，七國集團峰會正在巴伐利亞山區如火如荼地進行，而其他世界領導人已經抵達馬德里，參加被稱為北約防務聯盟多年來 "最關鍵 "的會議。
在過去，這些年度會議被認為是空談，充滿了含糊不清的承諾，而這些承諾的結果往往太少。例如，想想去年七國集團宣布的 "建設更美好的世界 "倡議。
But Mr Johnson is also right. Now is the time that Western leaders and their allies must make a serious impact if they are to counter Russian aggression and its fair-weather ally China in any meaningful way.
EU leaders gathered in Brussels before the weekend and the G7 summit is in full swing in the Bavarian mountains, while other world leaders are already arriving in Madrid for what's being billed as the "most crucial" meeting of the Nato defence alliance in years.
In the past, these annual meetings have been dismissed as talking shops, filled with vague-sounding promises, that too often result in too little. Think of the Build Back Better World initiative, announced at last year's G7, for example.
Leaders also pledged new sanctions on Moscow to limit its ability to import technologies for its arms industry. This, in addition a possible price cap on Russian oil exports, is designed to hit the Kremlin's war chest hard. But it's an initiative that can only work if enough countries, and the world's biggest economies most of all, are on board.
The need for Western unity
Joe Biden and Boris Johnson have members of their own party openly questioning their leadership; France's Emmanuel Macron just faced a bruising parliamentary election; Italy's Mario Draghi has seen his coalition partner, 5 Star, split down the middle; and Germany's Olaf Scholz's Social Democrat Party is divided over just how far and how long to keep Russia at arm's length.
All leaders say they support Ukraine. The EU threw convention to the wind on Thursday, offering Ukraine candidacy for EU membership - though it may take several years to make it into the bloc, if at all.
But Germany, Italy and France are more hesitant. They haven't quite let go of the idea, if not the hope, that Russia can still be a partner for dialogue further down the line. Whether in terms of business or wider security diplomacy, as Europe scrambles to re-design its security architecture which has been decimated by Russia's invasion and threats of nuclear strikes.
In fact one thing has remained resolutely unchanged in security terms since Russia's invasion of Ukraine: Europe has failed to stand on its own continental feet and still has a deep dependence on the US.
