Would you call the US aggressive and hostile? Would you call Russia aggressive and hostile? How about China? UK? France? South Korea? North Korea? Iran? Iraq? Lebanon? Turkey? (The list could go on and on)... Are these countries in the same situation you describe, i.e. fighting for their survival?
What exactly is the criteria to be considered aggressive and hostile? What would be a reasonable response to various security threats and hostile actions of others? If you apply that criteria fairly - that's fine. If you single out Israel, and filter the events to suit some agenda, maybe not so fine.
