Actually, a 10t-1 kiloton variable yield W54 weighted 23kg for about 30cm diameter. With thermonuclears, the weight to yield ratio is 4 Megaton per ton => 250kg= 1Mt, see the W59... We can reduce the weight and even making clean thermonuclears by replacing the 4.4kg of Pu239 used as a 1st stage primmer (you need a small A-bomb to trigger a H-bomb) by a little antimatter so cheap fuel like liquid deuterium can go fusion w.o an A-Bomb.
Binden doesn't wants to supply stuff that may strike Moscow for totally different reasons.
He perfectly knows that the Russians won't dare attacking the USA directly, BTW, they long brought stuff allowing Iran to attack US militaries in the Mid-East and the Soviets backed ALL terrorism against the West until Gorbachev came to power.
The real reason is the same USA drags feet on some deliveries and even refused that NATO taking care of transferring Poland's MiG-29s :
the goal is NOT the Russian invasion being promptly defeated !!!
Biden's goal is to weaken Russian military as well as f*ck-up its international status...
Even the arms sales are to fall : Russia has already lost half of its modern tanks, UVZ and ChVZ have even stopped production as targetting systems need western parts, so is it for the laser designation systems on aircraft : it's a licence-built outdated Thales Damocles, you need EU-made parts...
But with the turret throwing contest and Sukhois unable to achieve air superiority or SEAD, who wants to buy a T-90 or a Su-35 while a Soviet-era MiG-29 has just shot down a brand new Su-35?
How d'you think Russia's best client that is India feels?
BTW, Rafale is eating all Russian jets' traditional turf... and for good reasons: US even need to rig the competitions to sell their F-35...
By proceeding this way, Biden is dragging the Russian military into a total quagmire with gigantic gear losses, and 2 more months and they end with as much fatalities in 5-6 months as USA over 10 years in Vietnam! Moreover, Russia is not even attacking a serious client: Poland or Greece are way more powerful than Ukraine!!!
Moreover, 50-60% of Russia's exports normally go to the EU which actually prevented Russia from collapsing when the USSR crashed, and this was despite a trade deficit because, hey, what Russia imports from the EU is nowhere near what EU purchases from Russia and closed the eyes on many of Putin's and even Yeltsin's abuses...
Meanwhile Putin is doing shit, even interfering into EU' domestic policy by funding neo-fascists and neo-Nazi political-parties into the EU...
There were two, we sold'em to Egypt, and the sale was suspended as soon they invaded Crimea in 2014! There were no reasons to refuse when the contract was penned, before Killary/Obongo started to put pressure on Russia, they were willing to anchor with the west, including the EU and NATO, see
NATO Partnership for Peace :
Russia is still in, as well as in another NATO institution, the
Euro-Atlantic Partnership Council...
This is what happens when USA blocks ITAR certificates on spare parts for the C13-2 catapults, E-2C Hawkeye, E-3F Sentry to piss off France as well as pressuring its traditional clients away from buying Rafale, BTW, when you ruin our business in Iraq or our submarine sales to Australia, well, we have industries to run. I think we should resume proliferation, e.g. selling nukes to Taiwan, Korea, as well as creating an EU nuclear sharing : you crossed the Rubycon by selling nuclear submarines to Australia...
BTW, It was USA that funded the Vietminh and the Algerian FLN against us, both later turned to the Soviets against you and YOU created al-Qaeda. WE made the existence of the USA possible in 1775, you helped all European monarchies at crushing the young French Republic as soon as 1793... You were nowhere to be seen on any WW1 battlefield until July 1918, and it took you from 1939 to June 6th 1944 to remember where your oldest ally was located on a map during WW2, so, a good advise : never lecture your daddy who changed your diapers or be reminded the smell of your poo right under your nose...
Then, without USA's interferences, Ukraine would have started receiving Rafales for about 2-3 years now, but hey, you freaking want 100% of the market! You already have 85% of the NATO market for jet fighters whle not even selling the best ones, still not enough?
Then, what d'you think about the
US training of Russian VDV paratroopers in Colorado?
Oh, BTW, you surely remember
PEGIDA mass protests in Germany a few years ago? Do you know how these stopped? How funny, Merkel expelled ALL CIA operatives in the country. 4 weeks later, their weekly mass protests had shrunk to a few dozens of looneys...
And whatabout NSA taping the phones of all EU leaders and major business?
BTW, all this mess in Ukraine was caused by an US foreign policy named "Global Energy Dominance", this is why you did put pressure on Russia knowing that, as usual, they'd go bonkers and do something stupid !!!!
It's also why you corner Venezuela and fucked-up Libya or Iraq...
Now you're cornering Russia, how funny, Iran is no more under sanctions and has near tripled its economy and entered the G20... Now guess why MBS and MBZ refuse to talk to Biden and my 2cts Bennett is furious too!
Be aware that they're absolutely entitled at taking direct actions on Iran, accordingly to the Hague Convention, since Iran's proxies attack them all, and it's very probably in the pipeline, likely once UAE gets a few Rafales since the 4 Rezonans OTHRs Putn sold to Iran "see" F-35...
You'd better stop such little games on allies at US level, and at yours at starting lecturing your partners
