On the 28th of Nissan, 5750 (April 23, 1990) the Rebbe was notified that P.L.O. terrorists were threatening to attack various targets throughout the world. The following is the Rebbe's response, freely translated:
"I was notified that the P.L.O. has given instructions to all its branches worldwide to strike at targets throughout the world, G-d forbid.
"It is therefore necessary to invoke and emphasize the blessings from G-d to all Jews in all places, in all their needs. Primarily the most needed blessing is the miracle of the complete and perfect Redemption through Moshiach (whom we await every day that his coming not be delayed even as much as the blink of an eye). These blessings should be emphasized with complete trust and confidence, as well as with joy and gladness of heart.
"We should especially fulfill the directive of the Chabad Rebbes, 'Think good and it will be good.' "This means that thinking positively causes the course of events to actually turn out good. "This information should be utilized not to scare anyone, G-d forbid, but rather in the positive sense, to enhance the service of the Jewish people in the study of Torah and the observance of mitzvot.
"On the verse (Gen. 27:22), 'The voice is the voice of Jacob,' our Sages tell us that the power of the Jewish people is with 'our mouth.' Through our heartfelt prayers and Torah learning we can eliminate the plans of 'the hands of Esau,' the terrible schemes of our enemies.
"Thus there should be additional activities in Torah study and prayer and in mitzvot in general.
"Special emphasis should be placed on studying Torah diligently. For our Sages explain the verse, 'If you will follow my statutes' to mean that if you will labor in Torah... 'I will grant peace in the land. You will sleep without fear.'
"Through Torah study we eliminate all negative things and they are even transformed to good.
"Also, additional prayers should be said. Keeping with the spirit of 'thinking positive' it would be advisable to recite daily an extra three chapters of Psalms. One of these three chapters should be the final chapter of Psalms (ch. 150) which concludes with the verse, 'Let every being that has a soul praise G-d.' This means that every man, woman and child praises and gives thanks to G-d for His benevolence, and for the blessings and good fortune that He bestows upon us and will continue to bestow upon us.
"It would also be appropriate to add in the giving of charity. "Although 'fasting' is out of place (especially in the context of 'thinking positive') this does not contradict the giving of charity to redeem a fast. "It would be appropriate to give charity in the amount of two meals, and even better in the amount of three meals. This charity should preferably go to support people who learn Torah or institutions involved in disseminating Torah.
"Certainly these directives will be publicized in all Jewish communities, to all Jews, men, women and children.
"Emphasis must be placed however, to be very cautious not to scare anyone, G-d forbid. Rather, the purpose is to inspire everyone to enhance his/her Torah study and mitzvah observance, with truebitachon, complete trust and confidence in G-d, with joy and a glad heart. "The main thing is that the resolutions regarding the above should hasten and quicken the concept of 'think good and it will be good' in actuality starting from the ultimate good -- the complete and perfect Redemption through Moshiach."
