Vigorous, as the Israel Defense Forces use the word, means continuing sustained military action rather than stopping after any single confrontation. The IDF says it will keep pressing against Hezbollah following what the military describes as repeated attempts by that group to harm its troops.
That is the short version. The IDF is not announcing a new campaign. It is stating that the existing one will not let up.
The statement leans on the word "repeated" to describe Hezbollah's conduct. That framing is deliberate: a pattern of attacks, in the military's own telling, calls for a continuing response rather than a discrete counterstrike that concludes the matter.
What the statement leaves out is the specifics. The IDF offered no timeline and named no operation. It put its commitment on record. The details were not part of the message.
