Eurofighter Typhoon and before that the Panavia Tornado. That lineage's next up is the GCAP 6th gen plane.
Horizon/Orizonte and after that the FREMM (which is so good even the US are buying it). In general Italian/French naval cooperation is very strong.
The whole of MBDA and hell even Airbus were created for inter-country cooperation.
There are plenty of successful examples on which to build on, as well as failures from which to learn. But again, today very few military things cannot be sourced from a European supplier. BAE, Leonardo, Dassault, Thales, Rheinmetall, KNDS, Saab, Fincantieri, Naval Group, Indra, Airbus, MBDA etc. are world leaders in their respective fields.
> The reality is, if we the US make a deal with Russia over the Russian invasion of Ukraine in the next 12 months, the EU will have no choice but to accept it if you do not put boots on the ground and if you do not expropriate Russian government assets in the EU
No? US can sign whatever bootlicking deal it wants with Russia, but it's up to Ukraine what happens actually. The EU will continue backing Ukraine. Boots on the ground are highly unlikely, but exploration of Russian assets is quite probable (opposition isn't massive, and as time goes on, will only whither).
> We view the DSA as a non-tariff barrier to American services companies. This is both a Trump admin view [0] as well as a Biden-era admin view [1].
Cool, nobody cares. The US has put in sufficient actual tariffs that it cannot scream "unfair". EU leaders will try to negotiate whatever they can to lower short term economic damage, but the long term damage is done. The US is not a reliable trade or anything partner, and there's no going back on that.
Regarding your Mughal and Qing comparisons... Damn, where do I even start? EU isn't a country, so the comparison is off from the start.
