It’s in this speech: https://youtu.be/jeZJulgUuD8?si=Yfy2Y4Np3ws9hwjg&t=101

The English subtitle "we will operate forcefully everywhere" has a very different meaning from your quote: "We will target each and every corner of the strip."

What is the difference in the meaning?

"Target each and every corner of the strip" implies the strip as a whole is the target. "Operate forcefully everywhere" merely implies that force will be brought everywhere in the strip against whatever the target may be (from context, Hamas).

"operate everywhere" and "target each and every corner of the strip" are different citation, also do you speak Jewish or you relied on youtube autotranslate captions with questionable quality?

I speak Hebrew. The direct translation is "we will operate everywhere and with full force".
