【新闻趣读】
"疯子上帝"特朗普正在用"德州扑克式外交"改写世界规则——前一秒对伊朗说"咱们谈谈"，后脚就炸了人家核设施；一边搂着普京称兄道弟，一边威胁要把加拿大变成"第51个州"。这位把"反复无常"修炼成战略武器的总统，让欧洲盟友连夜把军费开支翻倍到GDP的5%，却可能意外促成伊朗加速拥核。下面请看BBC分析的"狂人理论"如何重塑全球格局——

Asked last month whether he was planning to join Israel in attacking Iran, US President Donald Trump said"I may do it. I may not do it. Nobody knows what I'm going to do".
当被问及是否会联合以色列打击伊朗时，特朗普总统回答："可能打，也可能不打，没人知道我要干嘛"。
He let the world believe he had agreed a two-week pause to allow Iran to resume negotiations. And then he bombed anyway.
他让全世界相信已同意两周停火期，转头就发动了空袭。
A pattern is emerging: The most predictable thing about Trump is his unpredictability. He changes his mind. He contradicts himself. He is inconsistent.
行为模式逐渐清晰：特朗普最大的确定性就是不可预测性——善变、矛盾、反复无常。
"[Trump] has put together a highly centralised policy-making operation, arguably the most centralised, at least in the area of foreign policy, since Richard Nixon," says Peter Trubowitz, professor of international relations at the London School of Economics.
伦敦政经学院国际关系教授彼得·特鲁波维茨指出："特朗普建立了高度集权的决策机制，堪称尼克松以来外交政策领域最集权的政府。"
"And that makes policy decisions more dependent on Trump's character, his preferences, his temperament."
"政策制定完全取决于他的性格、偏好和脾气。"

特朗普已将"不可预测性"转化为核心政治资产
Trump has put this to political use; he has made his own unpredictability a key strategic and political asset.
特朗普将这种特质政治化，使之成为关键战略武器。
He has elevated unpredictability to the status of a doctrine. And now the personality trait he brought to the White House is driving foreign and security policy. It is changing the shape of the world.
"不可预测教条"正主导美国外交安全政策，重塑世界格局。
Political scientists call this the Madman Theory, in which a world leader seeks to persuade his adversary that he is temperamentally capable of anything, to extract concessions.
政治学家称之为"狂人理论"——通过展现极端行为可能性迫使对手让步。
Used successfully it can be a form of coercion and Trump believes it is paying dividends, getting the US's allies where he wants them.
这种胁迫策略已初见成效：欧洲盟友被迫将防务开支提升至GDP的5%。
But is it an approach that can work against enemies? And could its flaw be that rather than being a sleight of hand designed to fool adversaries, it is in fact based on well established and clearly documented character traits, with the effect that his behaviour becomes easier to predict?
但该策略对敌效果存疑：当"不可预测"本身成为可预测的模式，是否反而削弱了战略威慑力？
Attacks, insults and embraces
攻击、侮辱与拥抱
Trump began his second presidency by embracing Russian President Vladimir Putin and attacking America's allies.
特朗普第二任期以拥抱普京、攻击盟友开场。
He insulted Canada by saying it should become the 51st state of the US.
他侮辱加拿大"应该成为美国第51个州"。
He said he was prepared to consider using military force to annex Greenland, an autonomous territory of America's ally Denmark.
扬言考虑武力吞并丹麦自治领地格陵兰岛。
And he said the US should retake ownership and control of the Panama Canal.
声称要收回巴拿马运河控制权。
Article 5 of the Nato charter commits each member to come to the defence of all others. Trump threw America's commitment to that into doubt.
北约第五条集体防御条款的承诺被特朗普动摇。
"I think Article 5 is on life support" declared Ben Wallace, Britain's former defence secretary.
英国前防相本·华莱士称："第五条正在重症监护"。
Conservative Attorney General Dominic Grieve said:"For now the trans-Atlantic alliance is over."
保守党总检察长多米尼克·格里夫断言："跨大西洋联盟已终结"。
A series of leaked text messages revealed the culture of contempt in Trump's White House for European allies.
白宫内部泄露短信显示对欧洲盟友的蔑视。
"I fully share your loathing of European freeloaders," US Defence Secretary Pete Hegseth told his colleagues, adding"PATHETIC".
防长皮特·赫格塞斯写道："我也厌恶欧洲搭便车者——可悲！"

防长赫格塞斯（右）称欧洲领导人是"揩油者"，副总统万斯（左）宣布不再保障欧洲安全
In Munich earlier this year, Trump's Vice-President JD Vance said the US would no longer be the guarantor of European security.
副总统万斯在慕尼黑宣布："美国不再保障欧洲安全"。
That appeared to turn the page on 80 years of trans-Atlantic solidarity.
这似乎终结了80年跨大西洋团结。
"What Trump has done is raise serious doubts and questions about the credibility of America's international commitments," says Prof Trubowitz.
特鲁波维茨教授认为："特朗普动摇了美国国际承诺的可信度。"
"Whatever understanding those countries [in Europe] have with the United States, on security, on economic or other matters, they're now subject to negotiation at a moment's notice.
"欧美所有安全经济协议都可能被随时重新谈判。"
"My sense is that most people in Trump's orbit think that unpredictability is a good thing, because it allows Donald Trump to leverage America's clout for maximum gain…
"其幕僚认为不可预测性有利可图，能最大化美国影响力..."
"This is one of his takeaways from negotiating in the world of real estate."
"这是他房地产谈判经验的延伸。"
Trump's approach paid dividends. Only four months ago, Sir Keir Starmer told the House of Commons that Britain would increase defence and security spending from 2.3% of GDP to 2.5%. Last month, at a Nato summit, that had increased to 5%, a huge increase, now matched by every other member of the Alliance.
策略立竿见影：英国军费占比四个月内从2.3%飙升至5%，北约成员国集体跟进。
