To answer your question as succinctly as I can—pressure from who?—the government wanted to avoid having Assange on US soil for a trial that would centre on US war crimes, especially at a time when Democrats are at risk of losing votes because of their support for similar crimes and an unfolding genocide in Gaza. They also never seriously thought they would be able to convict him, but wanted to torture him and see him broken both to neutralize him and to set an example to others. They got what they wanted, because he has now pled guilty to something that everyone with a basic understanding of the case—including the Obama DOJ—knows should have been protected speech. And I think you should care about that, because just like the escalating prosecution of whistleblowers in recent years (including under Obama), it sets a terrible precedent both for real journalists, and for all the cosplaying journalists who remained silent during his imprisonment and appeals. Outlets like the NY Times and Washington Post did not do anything materially different from what Assange did when they broke the stories from, and hand-in-hand with, WikiLeaks. I don't blame him for pleading guilty, because he deserves to be free. But this is a travesty and a disgrace. Assange is now free, but the state is also free to act with even greater impunity than it had before.
