WASHINGTON/BRUSSELS (Reuters) - The United States and its allies have mapped out detailed plans for coordinated, severe sanctions if Russian troops physically invade Ukraine, but how they should respond to other kinds of aggressions is far from agreed, U.S. and European officials say.

That ambiguity could slow the pushback Russian President Vladimir Putin will face if Russia repeats past tactics like identifiable cyberattacks, a disinformation campaign, or stepped-up support for pro-Russian separatists.
