Clarification: how long will it be agreed for, or how long will it last in practice? If the latter, what judges the “in practice”

@TomCohen Last in practice

@Bruce54df the standard pattern is that Hamas fires rockets at Israel immediately after the implementation of a truce, everyone gets mad, but every element of the truce aside from Hamas continuing to fire rockets goes ahead more or less without a hitch.

Would something like this count as the truce being broken?
